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​

Answer 1

Answer:

What happens when a solution of an acid  is mixed with a solution of a base in a test  tube.

=> iv. Salt formation takes place​

Explanation:

When an acid and a base solutions are mixed in a container (test tube here), they react together to form salt and water. This type of reaction is called neutralization reaction.

For eg :-

Formation of Sodium Chloride (Common Salt):

HCl + NaOH → NaCl + H2O

Answer 2

Answer:

i and  iv

Explanation:

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 and since it's a exothermic reaction the temperature of the solution increases.

Note:- IF YOU ARE OPTING FOR ONLY ONE OPTION THAN IT'S iv(SAME REASON) AND IF MORE THAN ONE THEN i and iv.
