The concentration of hydrogen ions ionized by water is 10 13, why can the solution be acidic or alka

Because the addition of acids and bases can inhibit the ionization of water.

Water neutral, room temperature, pH is 7, at this time, (h+)*oh—)=1*10 -14, this equation can be generalized to all aqueous solutions.

When the solution is pH = 13, that is, (H+) = 10 -13, at this time (oh-) = 10 -1, then the solution is strongly alkaline, and the hydroxide in the solution is ionized by the alkali, but the hydrogen ions in the solution.

It's all ionized by water.

pH = 1, just the opposite of the above, (oh-) = 10 -13, at this time (h =) = 10 -1, at this time the solution is strongly acidic, the hydroxide in the solution is ionized by water, but the hydrogen ions in the solution are ionized by acid.

It's a chemical reaction.

The simplest part of the behavior of the principle of aqueous solution, I believe you will gain a lot after reading the textbook! ^-

The concentration of hydrogen ions ionized by water is small, indicating a high concentration of acid or base in the solution.

Because. h2o h+ +oh- (the arrow in the middle represents the reversible sign) If the acid concentration is high, the acid has more hydrogen ions, which inhibits water ionization; The alkali concentration is high, and the alkali has many hydroxide ions, which also inhibits the ionization of water.

So you see.

Because acids or bases ionize H+ or OH- will inhibit the ionization of water, the concentration of hydrogen ions ionized in water is less than 10 -7 (especially at room temperature). If you have any questions, please feel free to ask. Thank you.

Because whether it's acidic or alkaline, it inhibits the ionization of water.

Not necessarily the solution may be acidic or alkaline.

For example, ammonia is added dropwise to a sulfuric acid solution.

There is a time when the inhibition of hydrolysis by acid and the promotion of hydrolysis by salt reach equilibrium, although it is acidic, but the ionization balance of water is not destroyed.

The ionization of water is not directly related to the solution.

For example, strong alkali and weak acid salt are alkaline.

However, the hydrogen ions ionized by water are greater than ten to the minus seventh power.

Hydropower ionizedHydrogen ionsThe concentration is 1x10-12, and the solution can be acidic or slowly alkaline. Hydrogen ions and hydroxide ions produced by water ionization.

Surely equal. and ch+*coh-=kw. In an acidic solution, hydroxide ions are produced by the ionization of water, then CH+ (ionized by acid) * COH- (ionized by water) = kw.

In an alkaline solution, hydrogen ions are produced by the ionization of water, then CH+ (ionized by water) * CoH- (ionized by base) = kw. As can be seen from the above two formulas, the solution can be either acidic or alkaline.

Chemistry:

Chemistry is a kind of natural science, which mainly studies the composition, properties, structure and change laws of matter at the molecular and atomic levels, and creates new substances (the essence is molecules that do not exist in nature). The world is made up of physical molds, and there are two main forms of change: chemical and physical (and nuclear reactions).

Different from particle physics and nuclear physics, which study the smaller scale, chemistry studies the material structure of atoms, molecules, ions (clusters), chemical bonds, and intermolecular forces.

and other interactions.

There are two scenarios when the solution is acidic or alkaline. One is the direct ionization of acid and base, and the other is the hydrolysis of salt. When the water is ionized h+=10x -13, it should be the direct ionization of acid and base, whether it is acidic or alkaline, the h+ and oh- separated from the water and electricity leakage hall are the same.

Therefore, the celery can be acidic or alkaline.

Are you funny? H+ and oh- are always equal when water is ionized, so why is oh- 10-13 and h+ 10-1?

The H+ concentration referred to by pH in the solution is the total H+ concentration of the mountain, except for H2O ionized H+, is the acid not ionized? All you calculate from the ion product constant is that the equilibrium is total h+* total comma oh-=10-14, but who says that h+* oh-=14 of water is water?This must be a condition that can only be met in pure water.

The hydrogen ions and hydroxides ionized by water refer to the separation of hydroxide and hydrogen ions into hydroxide and hydrogen ions in the water closed ear field molecules, and their tremor concentrations must be the same, but whether the amount is the same is not necessarily, the situation you said can be hydrochloric acid with pH equal to 1, at this time, the hydrogen ions in the solution are the hydrogen ions in hydrochloric acid, not the hydrogen ions ionized by water, and the hydroxide ionized by water is 10 -13

So the ionized hydrogen ions are also 10 -13

You have to think more about this knowledge.

Remember the hint I gave you earlier.

I hope that the sedan chair will help you.

Do you see your own problems clearly ...

C(OH-)=10-12 mol L produced by water ionization, the first possibility: the solution is acidic, and the C(Oh-)=10-12 mol L produced by water ionization, then the concentration of H+ produced at the same time C(H+)=10-12 mol L, according to the ionic product constant of water, C(H+)=10-2 mol L, pH 2 in the solution.

The second possibility: the solution is alkaline, pH = 12, and the water ionization produces c(OH-) = 10-12 mol l.

The c(oh-) ionized by water is 10 -13 mol l, but there must be c(h+)*c(oh-)=10 -14 in the solution, that is, it may be an acid solution with pH 1 or an alkali solution, because the solution with pH 1 and pH 13 can inhibit the ionization of water.

H2O=OH- +H+ (reversible).

Above is the electrolysis of water, and it can be found that the hydroxide ions ionized by water are the same as the hydrogen ionization naurion. In a neutral solution, hydroxide ions and hydrogen ions are both 10 (-7) mol l, and the reason why they decrease is because the ionization of water with Liang is inhibited, and according to the chemical equilibrium, it can be known that both acid and alkali will inhibit the ionization of water.

So the concentration of hydrogen ions ionized by water is equal to 10 -14, why can the solution become alkaline or acidic.

It may be a strong acid, and it may be a strong base.

The concentration of hydrogen ions ionized by water is 1x10 -13, and the concentration of hydroxide in water ionization is always 1x10 -13, so the concentration of hydrogen ions in the solution may be or the concentration of hydroxide ions, so it may be both a strong acid and a strong base.

Summary. Hello, because the concentration of hydrogen ions ionized by water is 1x10-2 greater than the concentration of hydrogen ions in pure water 1x10-7, so it is a strong acid and alkali solution. I hope mine is helpful to you.

The concentration of hydrogen ions ionized by water is 1x10-2 why is it acidic.

Hello mu socks, because the concentration of hydrogen ions ionized by water is 1x10-2 greater than the concentration of hydrogen ions in pure water 1x10-7, so it is a strong acid and alkali solution. I hope you find my scrambler helpful.

Does it have to be a strong acid solution?

That's right, you just have to remember that.

If you think about it, if it is an alkaline solution, then its hydroxide will react with hydrogen ions, consume hydrogen ions, and combine into water to destroy dust, so there are fewer hydrogen ions in the water. This is easy to understand.

The hydrogen ions and hydroxide ions produced by the ionization of water are certainly equal. and ch+*coh-=kw.

In an acidic solution, hydroxide ions are produced by the ionization of water, then CH+ (ionized by acid) *COH- (ionized by hydropower) = kw

In alkaline solution, hydrogen ions are ionized by water to produce Zen bark, then CH+(water-ionized)*Coh-(alkali ionized)=kw

As can be seen from the above two formulas, the solution can be either acidic or alkaline.
