Explanation: 2 Marks
Reaction Diagram: 1 Mark
Changes: 1 Mark
Reason: 1 Mark
The reaction between an acid and a base is known as neutralization. Salt and water are produced in this process with the evolution of heat.
Acid+ Base → Salt + Water + (Heat is evolved)
As for example, when sodium hydroxide (NaOH) is treated with sufficient amount of hydrochloric acid (HCl), a neutralization reaction takes place. Both NaOH and HCl neutralize their effects and form a salt sodium chloride (NaCl) and water (H2O) with the evolution of heat energy.
NaOH + HCl → NaCl + H2O + (Heat is evolved)
Whensulphuric acid is added to lime water, the reaction mixture will become hot because it is a type of neutralizationreaction. An acid is mixed with a base.
So, heat will be evolved in this reaction.
