Question 3
What happens when a solution of an acid is mixed with a solution of a base in a test
tube?
(1) The temperature of the solution increases
(i) The temperature of the solution decreases
(ii) The temperature of the solution remains the same
(iv) Salt formation takes place
​

Answer 1

option.4(Salt formation takes place)

is correct .

When acid is mixed with a solution of base it results in a neutralization reaction. Neutralization is an exothermic reaction which results in the formation of salt. When an acid reacts with a base, a neutral salt is formed by the neutralisation process. As neutralisation process is an exothermic reaction, the temperature of the solution increases
