Arrange the following in increasing order of ph:
`KNO_(3)(aq)`,`CH_(3)COONa(aq)`,`NH_(4)CI(aq)`,`C_(6)H_(5)COONH_(4)(aq)`

Text Solution

Verified by Experts

Increasing order of ph implies decreasing acidic strength and increasing basic strength. The correct order of increasing ph is
`NH_(4)CI(aq),C_(6)H_(5)COONH_(4)(aq),KNO_(3)(aq),CH_(3)COONa(aq)`
