What happens when sulphuric acid dissolves in water?

Answer 1

Nothing significant happens. You only make the acid dilute or you reduce the concentration of that acid. As a result, it becomes less dangerous. Even sulphuric acid had once fallen on my fingers, but luckily it was dilute.

Heat will be generated, the amount dependent on the quantity and concentration of the acid. This amount of heat may be significant....

Answer 2

When sulfuric acid dissolves in water, it releases hydrogen ions (H+) and sulfate ions (SO4^2-). This process is highly exothermic and produces heat. The resulting solution is highly acidic, with a pH level below 7.

Answer 3

Heat is generated and temperature of the solution increases. (Never add sulfuric acid to the water. It can explode and serious injury may be caused. Always add water to the sulfuric acid and that to carefully.)

Answer 4

It turns into sulfuric acid. Then add salt, and it becomes hydrochloric acid. Awesome, huh? I have some sulfur, and I am going to try it.

Answer 5

Sulfur and water do not react. The sulfur has to react with oxygen first to form SO2 . The SO2 and water can then react to form sulfurous acid.

Answer 6

Hydrogen sulphide results from combining hydrogen and sulfur.

Answer 7

Sulphurous acid is formed

H2O + SO2 ----> H2SO3

Answer 8

When sulfur is mixed with water there is NO chemical reaction (change), so there's no reaction equation.

Answer 9

No solution, as sulfur is not soluble in water.

Answer 10

H2SO4 + H2O --> HSO4- + H3O+

Sulfuric acid is a strong acid and so it dissociates completely to form the hydronium ion, which is the sign of an acid.
