Question

If approximately equal volumes of an acid and a base of equal strengths are combined, the resulting solution should have a pH of _____.

Answer 1

Answer : The resulting solution will have a pH of 7.

Explanation:

Whenever acid and base reacts with each other to form water molecule is called Neutralization reaction. This water molecules is formed from the  hydronium ion ($H^+$) from acid and hydroxide ion($OH^-$) from base.

When the equal volumes of acid and base of equal strength are combined, the resulting pH of the solution becomes 7.

The pH 7 value means that the solution is neutral.

Answer 2

If approximately equal volumes of an acid and a base of equal strengths are combined, the resulting solution should have  pH of  around 7.
