Equal volumes of M NaOH and 0.3 M KOH are mixed in an experiment. Find the POH and pH of the resulting solution.

Text Solution

Verified by Experts

`N=(N_(1)V_(1)N_(2)V_(2))/(V_(1)+V_(2))`
`N=(x(0.5)+x(0.3))/(x+x)` Given value equal.
`=(0.8)/(2)=0.4=[OH^(-)]`
`pOH=-log[OH^(-)]`
`=-log(0.4)`
`0.3979`
`=13.6021`
