Question

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 (iii) 

C. (ii) and (iii) 

D. (i) and (iv)

Answer 1

When a solution of an acid is mixed with a solution of a base then the temperature of the solution increases as it is an exothermic reaction and the corresponding salt formation takes place.
