The correspondence between the quantity, concentration and density of the sulfuric acid solution sub

The concentration of the sulfuric acid solution (mass fraction.

There is no direct relationship with the amount of sulfuric acid, and an indirect relationship can occur through the quality of the sulfuric acid solution, when the mass of the sulfuric acid solution is constant, the greater the concentration (mass fraction) of the sulfuric acid solution, the greater the amount of sulfuric acid, and the proportional relationship.

The concentration of sulfuric acid solution (quantity concentration) is not directly related to the amount of sulfuric acid, and the indirect relationship can occur through the volume of sulfuric acid solution.

The density of sulfuric acid solution is not directly related to the amount of sulfuric acid, and the indirect relationship can occur through the mass and volume of sulfuric acid solution.

The density of sulfuric acid solution is directly related to the concentration and mass fraction concentration of sulfuric acid solution, and the different concentrations and mass fraction concentrations of sulfuric acid solution correspond to the density of a sulfuric acid respectively, which can be found from the concentration and density of sulfuric acid comparison table.

98% of the sulfuric acid solution density is, the amount concentration of the substance is, 15% of the sulfuric acid solution, the density is, the amount concentration of the substance is.

The higher the concentration, the greater the density, the density of the concentrated sulfuric acid solution and the amount and concentration of the substance can be measured and calibrated by the actual measurement and calibration, and then the actual concentration can be obtained by the formula c=1000 m, and the same is true for other strong acids.

The sulfuric acid density and concentration comparison table is as follows:

<> the density of sulfuric acid g cm, the concentration of pure sulfuric acid is sulfur.

Sulfuric acid is an inorganic compound with the chemical formula H2SO4, which is the most important oxygenated acid in sulfur. Found in the 8th century AD. The Arab alchemist Jaber obtained sulfuric acid by dry distillation of ferrous sulfate crystals.

Acid rain contains sulfuric acid, and sulfur dioxide (SO2) in acid rain reacts with water in the atmosphere to form sulfurous acid (H2SO3).

Because sulfuric acid is denser than water, the higher the concentration of sulfuric acid, the smaller the content of water, so the greater the concentration of sulfuric acid, the greater the density. And the density of sulfuric acid is greater than that of water, because the density of sulfuric acid is gram cubic centimeter, and the density of water is 1 gram cubic centimeter.

The mass of the solute does not change before and after dilution.

That is, m pre-plasm = m post-quality.

Pre-M Fluid A = M Post-Liquid A

Pre-solution 98 =

v pre-solution = (this is the volume of concentrated sulfuric acid).

Water needs = m post-liquid - m pre-liquid = =

Then water needs , concentrated sulfuric acid needs.

The greater the density of the H2SO4 solution, the greater the mass fraction of sulfuric acid.

The smaller the density of the ammonia solution, the greater the mass fraction of ammonia.

This requirement can be deduced, some physical quantities will be assumed, and inequalities will be used. I don't want to push, the same goes for ammonia, I give the principle, the two methods complement each other.

Because pure liquid ammonia is less dense than water.

So the higher the concentration of ammonia, the closer it is to the density of liquid ammonia.

So the smaller it is, the more similar the sulfuric acid principle.

I'll give you the data proof.

The concentration of the sulfuric acid solution, the mass fraction and density of the solute.

Density of (20)g cm3 H2SO4 mass fraction 100 g solution. Quantity concentration of the substance (mol l) density (20 ) g cm3 mass fraction of H2SO4 g 100g solution, quantity concentration of the substance (mol l).

Hope I can help you.

Positive correlation. The higher the mass fraction, the higher the density.

The higher the mass fraction, the higher the density.

The concentration of sulfuric acid solution (density = the amount of the substance is (

Set the volume to 1 ml, the concentration of the amount of the substance cb = (1 2If 50ml of the concentrated sulfuric acid is dissolved in water to obtain 500ml of dilute sulfuric acid (the volume of the solution lost in the process is not counted), the concentration of the substance of the dilute sulfuric acid solution is (

The concentration of the amount of the substance cb = (50

3.Now with 98% concentrated sulfuric acid (density = 500ml of dilute sulfuric acid with a concentration of 500ml, the required volume of concentrated H2SO4 is (

The concentration of the amount of the substance cb = the amount of the solute of the substance and the volume of the dissolved solution.

The amount of H2SO4 required is 500ml of dilute sulfuric acid at a concentration of 500ml

The volume of concentrated H2SO4 required is xml, then (x, x=

The mass of the solute brother remained unchanged before and after dilute disturbance.

That is, m pre-plasm = m post-quality.

Pre-M Fluid A = M Post-Liquid A

Pre-solution 98 =

v pre-solution = (this is the volume of concentrated sulfuric acid).

Water needs to be the first imitation to = m after the liquid - m before the liquid =

Then water is needed.

Concentrated sulfuric acid is required.
