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.
[tex]pH=-\log [H^+][/tex]
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
