How to calculate the concentration of industrial sulfuric acid and what is the concentration of conc

First, find the concentration of 1ml of industrial sulfuric acid equivalent. Sulfuric acid equivalent concentration Sodium hydroxide equivalent concentration = Sodium hydroxide volume Sulfuric acid volume. Sulfuric acid equivalent concentration = 1 times.

The gram equivalent of sulfuric acid is 1 2 molar mass grams of sulfuric acid.

The weight of 1 ml of sulfuric acid = the gram equivalent of sulfuric acid multiplied by the equivalent concentration of sulfuric acid multiplied by the volume of sulfuric acid (1ml) 1000 = grams).

Then, the concentration of 1 ml of sulfuric acid (weight to volume ratio g l) is multiplied by 1000=

The formula for calculating the concentration or volume of acid-base neutralization is:

Acid equivalent (ns) * acid volume (vs) = base equivalent (nj) * base volume (vj) simplified to obtain: ns*vs=nj*vj ;

There is a calculation formula according to the meaning of the question:

ns*1ml=1n*

ns=1n*

Because sulfuric acid is a dibasic acid, its molar concentration is its equivalent when it is "one".

The concentration is "two", so the concentration of this industrial sulfuric acid is:

The molar concentration of sodium hydroxide is equal to its equivalent concentration).

Ferrous sulphate. There are assay methods.

Concentrated sulfuric acidThe concentration is:

Mass fraction of H2SO4 in commonly used concentrated sulfuric acid.

for, its density is. , melting point: 10; Boiling Point:

338℃。Sulfuric acid is a strong acid with a high boiling point and difficult to volatilize, which is soluble in water and can be miscible with water in any ratio. When concentrated sulfuric acid is dissolved, a large amount of heat is released, so when concentrated sulfuric acid is diluted, it should be "acid into water, along the wall of the vessel, slowly poured, and constantly stirred".

Concentrated sulfuric acid is an aqueous solution of sulfuric acid with a mass fraction greater than or equal to 70%, commonly known as bad water. Concentrated sulfuric acid is highly corrosive: at atmospheric pressure, boiling concentrated sulfuric acid can corrode all metals except iridium and ruthenium, and the number of elemental metal species that can be corroded even exceeds that of aqua regia.

Sulfuric acid has strong oxidizing properties at high concentrations, which is one of the biggest differences it has from dilute sulfuric acid. At the same time, it also has dehydration, difficult volatility, acidity, water absorption, etc. with nitric acid.

Similarly, the reducing product is affected by the reducing agent.

The type and amount of the effect may be sulphur dioxide.

Sulfur elemental or sulfide.

Strong corrosiveness: concentrated sulfuric acid has a strong corrosiveness, if the experiment is accidentally splashed on the ** or clothes, should be immediately rinsed with a large amount of water, not only can reduce the time of concentrated sulfuric acid on the **, but also dilute the concentrated sulfuric acid in the first time, reduce its harm to the human body, and even if it is dissolved in water will have heat release, but a large number of facts have proved that the running water will take away the heat during washing, and the heat generated has almost no effect on the human body (remember not to wipe with a cloth, because concentrated sulfuric acid has strong dehydration, and it will be carbonized after contact, If you wipe it with a cloth, you will wipe off the ** tissue.

However, if you need to answer on the test paper, the content of the textbook shall prevail), and then apply 3% 5% sodium bicarbonate.

solution (Sodium hydroxide should never be used.)

isostrong bases). If it is severe, it should be taken to the hospital immediately. If the dripping falls on the table during the experiment, wipe it dry with a cloth.

The above content reference: Encyclopedia - concentrated sulfuric acid.

The concentration of concentrated sulfuric acid is generally greater than or equal to 70% sulfuric acid solution. Oleum is not included.

Concentrated sulfuric acid has strong oxidizing properties at high concentrations, which is one of the biggest differences between it and ordinary sulfuric acid or ordinary concentrated sulfuric acid. At the same time, it also has dehydration, strong oxidation, refractory volatility, acidity, stability, anti-combustion and water absorption, etc. Dilute sulfuric acid is generally only acidic.

The concentration is molarity of sulfuric acid consumes 2 moles of sodium hydroxide.

Sulfuric acid concentration = 1x8 (2x2) = 2 mol liters.

Concentration expressed in moles of liters. Not a percentage concentration.

2*2, the first 2 means that 1 mole of sulfuric acid consumes 2 moles of sodium hydroxide;

The second 2 means 2 ml.

For example: the volume of the solution to prepare C(H2S04)=1mol L is:

Let the density of 1mol l sulfuric acid solution be d

The quality of the water that needs to be added is:

If d is approximately considered as 1, then the mass of the added water is:

1840-184 = 1656 grams = 1656 ml.

1656ml of distilled water is required.

Basic formula: c = 1000 98

where c is the concentration of sulfuric acid;

is the density of sulfuric acid in g ml;

is the mass fraction of sulfuric acid, %.

The formula can see that if you know two of the three unknowns, you can calculate the third.

First of all, you need to know what is the concentration of sodium hydroxide solution you are using.

The concentration of pure sulfuric acid is sulfur.

Sulfuric acid is an inorganic compound with the chemical formula H2SO4, the most important oxygenated acid of sulfur. Pure sulfuric acid is a colorless, oily liquid, crystallized when it is deficient, and it is usually obtained by using its aqueous solutions of various concentrations, using the tower method and contact method. The former is obtained as crude dilute sulfuric acid, mass fraction.

Generally around 75%; The latter yields concentrated sulfuric acid in mass fraction.

Boiling point 338, relative density.

The degree of dense turbulence of concentrated sulfuric acid is approximately.

Therefore, the molar concentration of the deficit town is 1000 * large gap 8=
