What happens when a solution of an acid is mixed with a solution of a base in a test tube?
(i) Temperature of the solution decreases
(ii) Temperature of the solution increases
(iii) Temperature of the solution remains the same
(iv) Salt formation takes place
(a) (i) and (iv) (b) (i) and (ii)
(c) (ii) only (d) (i) and (iv)
Correct Answer: (d) (i) and (iv)
Explanation: When acid is mixed with a solution of base, it results in a neutralization reaction. Neutralization is an exothermic reaction that results in the formation of salt.
