If approximately equal volumes of an acid and a bace of a equal strength are combined the resulting solutin should have a ph of
around 7
above 7
below 7
impossible to determine

The answer is around 7.

As the acid and the base are of equal strength, they neutralize each other and the resulting solution is neutral (pH≈7).

Hope this helps you!

Answer : The correct option is, around 7

Explanation :

pH : It is defined as the negative logarithm of hydrogen ion or hydronium ion concentration.

The pH range is, 1 to 14.

When the value of pH is less then 7 then the solution will be acidic.

When the value of pH is more then 7 then the solution will be basic.

When the value of pH is equal to 7 then the solution will be neutral.

As per question, when approximately equal volumes of an acid and a base of a equal strength are combined then the resulting solution should have a pH of  around 7 because when equal amount of acid and base are combined it form neutral solution and the neutral solution has pH around 7 or equal to 7.

Hence, the correct option is, around 7
