What happens when a solution of an acid is mixed with a solution of a base in a test tube?- The temperature of the solution increases
- The temperature of the solution decreases
- The temperature of the solution remains the same
- Salt formation takes place
(a) (i) only
(b) (i) and (iii)
(c) (ii) and (iii)
(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.
