Question

The aqueous solution of which of the following has maximum pH ?

• A. NaCIO
• B. $NaC1O_2$
• C. $NaCIO_3$
• D. $NaC1O_4$

Answer 1

Answer: (A)

NaCIO

Answer 2

Maximum pH means most basic. Therefore solution of NaCIO (salt of a strong base with the weakest acid out of $HCIO, HClO_2, HCIO_3$ and $HClO_4$) in water will be most basic and as such will have highest pH
