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 temperature of the solution remains the same
(iv) Salt formation takes place

A

(i) only

B

(i) and (ii)

C

(ii) and (iii)

D

(i) and (iv)

Text Solution

Verified by Experts

The correct Answer is:
