Please explain exactly what the ion concentration is and how much charge the ion has

Okay, the ion concentration is only the number of ions per unit volume of solution, for example, if there are 2na sodium ions in 1 liter of saline, then the concentration of sodium ions is 2mol l, if there are 3nage1 sodium ions in 1 liter of saline, then the concentration of sodium ions is 3mol l, the charge carried by the example refers to a single one, for example, 1 sodium ion has 1 unit positive charge, and 1 magnesium ion has 2 units of positive charge!

Regarding that example, hydrochloric acid is HCl, ammonia is NH3, NH3 is formed in water, and ammonia hydrate reacts with hydrochloric acid to form ammonium chloride, both ammonium chloride and HCL are strong electrolytes, so the conductivity of the solution remains the same.

Ion concentration: refers to the concentration of a certain ion in the solution, which can be found from the concentration of the solution, and the ion concentration in the example is equal to the concentration of the solution!

The charge of the ion: it depends on the valence ion of it, for example, mg is 2, cl is 1; The amount of charge in the example has not changed, NH4Cl is formed by the HCL reaction, the charge of the ions is the same, and the concentration of the solution has not changed, so the conductivity of the solution does not change, so the ammeter reading remains the same!

The ion concentration, for example, sodium chloride, dissolves it into one liter of water to obtain 1mol l of sodium chloride solution, because there is one sodium and one chlorine in sodium chloride, so the concentration of chlorine atoms in the solution is 1mol l = the concentration of sodium ions. The same goes for the others.

Let's talk about this problem, because the original HCl solution has 1mol L of hydrogen ions and 1mol L of chloride ions, after the ammonia gas is introduced, HCl+NH3==NH4Cl, after the ionization of ammonium chloride, there are still 1mol L of chloride ions and 1mol L of ammonium ions, and the sum of the charges of all the ions before and after is unchanged, which is 1+1=1+1, so the conductivity remains unchanged.

Ionic charge refers to a single anion or cation. Conductivity is proportional to the sum of the absolute values of the various ionic charges and their concentrations.

When ammonia is introduced, the reaction NH3 + H+ = NH4+ occurs, the cation concentration and charge are unchanged, and the anion is also unchanged, so the conductance (equal to the reciprocal of the resistance) does not change, and the meter reading does not change.

It depends on what kind of ion it is, mainly referring to the absolute value of the charge carried by the ion.

If we compare S2- and Cl-, then of course the ion charge number of S is large.

If Cl7+ and S6+ are compared, of course, the ionic charge number of Cl is larger.

Ion concentration refers to the number of vertical early ions formed in a certain solution divided by the volume of liquid deficits, for example, taking NaCl (salt) as an example, two ions will be produced in the solution, Na+ and Cl-;

The charge number refers to the number of charges on each ion, for example, taking NaCl (salt) as an example, Na+ and Cl- each have 1 charge;

If you switch to other salts, such as sodium carbonate.

The chemical formula Na2CO3), where the number of ions on the surface becomes 2 Na+T and 1 CO3-2, and the number of charges becomes 4, 2 positive and 2 negative. (Because the solution is neutral, the positive and negative are canceled).

In this way, you can understand why the charge concentration is equal to the ion concentration corresponding to the charge number x.

Not equal. If the central atom (ion) is associated with the anion.

Coordination, then the number of charges carried by the ligand ion and the number of charges carried by the central ion are generally not equal. For example, [Fe(scn)6]3-, [CuCl4]2-, etc. Nawei.

Applications

Due to the complexes.

It is electrically neutral, therefore, the total charge of the external ion is equal to the total charge of the ligand ion, and the sign is reversed, so the charge of the ligand ion and the oxidation value of the central atom can be inferred from the charge of the external ion.

For example, in K4[Fe(CN)6], the total charge of the external ions = 4x(+1) =4, so the charge of the matching ion Chang Lipei is -4, and the oxygen rot disturbance value of the central atom iron can be deduced as Fe(II).

than slag removal, such as: Fe3+ 3+

Concentration (mol l) 1 3

Concentration (mol l) x 3x

From the above circle, it can be seen that the charge number 3 multiplied by the corresponding ion concentration is the concentration of the charge, because the same brigade bend is quietly in the same system, the volume is the same.

Okay, so how can the teacher tell if a compound is made of atoms or ions by its chemical formula?

Generally speaking, if the chemical formula is not the simplest ratio, it must be the molecular composition. The other two need to be reduced to the simplest such as NaCl, C. When the bond is the simplest, it is also possible that the molecule, such as AlCl3 (in fact, Al2Cl6).

If you see ionic compounds, they are all made of ions, such as NaCl MgSO4 NH4NO3.

What do you mean?

<> this meaning is this meaning pro.

That is, the greater the value of the ion's bond, the greater the charge of the ion.

(generally proportional to the product of their charges).

NaCl, which is made up of sodium ions and chloride ions, both of which are ions with a unit charge.

MGO, which is composed of magnesium ions and oxygen ions, is known to be ions with a two-unit charge.

The ionic bond of MGO is stronger than that of NaCl, making the oxide of the skin auspicious magnesium.

The melting boiling point is higher than sodium chloride.

The hardness is greater than that of sodium chloride.

Hello dear, knowing the atomic mass and spike field concentration of an ion, the following parameters can be calculated:1Ionic Charge:

The ionic charge is obtained by dividing the atomic mass of that ion by the atomic number of the atom. In a chemical reaction, the charge of an ion determines the chemical properties of the ion in the reaction. 2.

Ionic Radius: The ionic radius is the atomic mass of the ion divided by the ionic charge, and then the square root is taken. The ionic radius is a parameter of the size of the ion, and it can be used to describe the degree to which the ion is dispersed in solution.

3.Molar mass of an ion: The molar mass of an ion is the atomic mass of the ion multiplied by the number of ionic charges, multiplied by the ionic ashwagandha index of the ion.

In solution, the molar mass of an ion determines the mass change of the ion in a chemical reaction. 4.Charge density of ions:

The charge density of an ion is the number of charges of that ion divided by the ionic radius. The charge density of an ion can be used to describe the distribution of ions in a solution.
