Answer 1

Answer:

iv

Explanation:

because acids and bases of particular pH give neutral value 7

Answer 2

Answer:

second option

Explanation:

because in the question it is not mentioned how strong the acid or base is and how much quantity is added. If acid and base are added in any proportion, then the solution may not be neutral.Therefore if both are neutral, you will surely get a neutral solution.
