what happens when a solution of an acid is mixed with a solution of a base in a test tube ?
(i) The temperature of the solution increases
(ii) The temperature of the solution decreases
(iii) The temperatue of the solution remains the same.
(iv) salt formation takes place.

Options

A. Temperature of the solution decreases.
B. Temperature of the solution increases
C. Temperature of the solution remains the same
D. None of the above

Answer

B

Explanation

Salt and water are made by combining acid and base. This process is exothermic in nature, releasing heat known as heat of neutralisation, causing a temperature to increase. When acid is added to any base, the temperature of the acid-base reaction rises.
