Conc.H2SO4 dissolves in water liberating a lot of heat.Why?
Asked by prodyumna02 | 31st Jan, 2019, 12:27: PM
The reaction of sulphuric acid with water called a hydration reaction in which a large amount of heat is produced hence it is an exothermic reaction.
When water is added to sulphuric acid, it can boil and spit dangerously.
This type of behavior is related to the relative densities of the two liquids.
Sulphuric acid is denser than water hence water will tend to float on the acid, which leads to the formation of a large amount of heat.

- 13. Write the balanced chemical equation to support each of the statements given below (use only dilute sulphuric acid). a. Basic oxide + acid → salt + water b. Metallic carbonate + acid → salt + water + carbon dioxide
- Name the gas evolved when: dil. sulphuric acid reacts with sodium sulphite. Give the balanced chemical equation of the reaction as well.
- we know water is a non electrolyte since it requires h2so4 to ionize to positively harged hydronium ions and sulphate ions then what property of water makes itself ionize to h+ and oh- ions along with the ionization of the dissolved salts ?? is it so if then why??
- Sir/Madam, kindly answer the following: Why is direct addition of dil. H2SO4 to PbCO3 an impractical methof of preparing lead sulphate?
- give a chemical test to distinguish between dil.sulphuric acid and conc.sulphuric acid
- 1)write a equation when hot and concentrated sulphuric acid reacts with sodium hydroxide. 2)concentrated sulphuric acid is kept in air tight bottle.give reason 3)sulphuric acid is not used as drying agent for H2S.
- How is dil.Sulphuric acid prepared from Conc Sulphuric acid?
- Why does dil.H2so4 form 2 types of salt with an alkali?
