Question

1.
Why do we calculate the heat evolved for the neutralisation of 1000 mL of (1M) aca
by 1000 mL of (1M) monoacidic base ?​

Answer 1

We need to calculate the heat evolved to determine whether the temperatre of the solution has increased or decreased.

Explanation:

• In a neutralization reaction, an acid reacts with a  base and releases an adequate amount of heat as the result of neutralization.
• The neutralization reaction is always exothermic reactions.
• The heat evolved as a result of the reaction is known as the molar heat of neutralization.
• The formula to calculate the heat evolved is
• ΔH = Q / n
• Heat evolved in measured in KJ/mol.
