Question

Boojho added dilute sulphuric acid to lime water. Will the reaction mixture become hot or cool

Answer 1

Hey friend ,
________________________________
Answer is :- Hot
$\boxed{EXPLANATION:-}$

When dilute sulphuric acid to lime water (calcium hydroxide ) it becomes calcium sulphate .
When an acid +base reaction takes place the reaction releases heat energy .
So this process releases heat energy .
This reaction is also called exothermic reaction which releases heat or light energy.

Answer 2

Answer:

Concept:

One or more hydrogen ions are exchanged during an acid-base reaction, a kind of chemical reaction. Calcium sulphate (CaSO4) and water are produced when diluted sulfuric acid is introduced to lime water. Because the reaction involves a strong acid and a strong base, it is often referred to as an exothermic reaction because more heat is produced during the process. Calcium hydroxide, sometimes known as lime water, is another name for free lime, which is insoluble in water.

Explanation:

• When the diluted (H2SO4) is combined with lime water (Ca(OH)2), the reaction produces calcium sulphate (CaSO4), which when combined with water (H2O) and neutralised produces an exothermic reaction.
• The water forms a covalent link and releases energy, exhibiting exothermic behaviour.
• Free lime, which is insoluble in water, is sometimes referred to as calcium hydroxide, often referred to as lime water.
• Dilute Sulphuric acid is added to lime water and the reaction mixture will become hot.
