Question

Which solution has the maximum pH?

• A. $1M\text{-}KOH$
• B. $10M{H}_{2}S{O}_4$
• C. Chlorine-water
• D. Water containing carbon-dioxide

Answer 1

Answer: (A)

The pH of 1 M-KOH will be the highest $\text{Ist pH}=14-\text{pOH}$ $=14-\text{log }[\text{ O}{\text{H}}^{-}]$ $=14+\text{log }1$ $=14+0=14$
