Question

PH concentration to that of water is given below. Water has PH of 7
$\begin{array}{cccc}Liquid& PH& Liquid& PH\\ H2SO4& 2& HCL& 2.5\\ NaOH& 12& H2O& 7\\ MnOH& 8.5& CuSO4& 7\end{array}$
Neutralize a mixture means bringing to PH of 7. PH of a mixture is weighed average of the PH of the components (liquid) present in the mixture.
A solution has an equal percentage mixture of H2SO4 and NaOH. What is the minimum percentage of liquid from amongst the table we should add to bring the PH concentration level equal to that of water?

• A. 20%
• B. 60%
• C. 15%
• D. None of these

Answer 1

The correct option is D None of these

Option (D) is the correct answer. Check the video for the approach.
