$0.02 \, N$ basic

Vedclass · Answer

(A) The number of equivalents of acid $(N_1V_1)$ = $20 \, mL 	imes 0.25 \, N = 5 \, meq$.The number of equivalents of base $(N_2V_2)$ = $30 \, mL 	imes 0.2 \, N = 6 \, meq$.Since the number of equivalents of base is greater than the acid,the resulting solution will be basic.Excess equivalents of base = $6 \, meq - 5 \, meq = 1 \, meq$.Total volume of the mixture = $20 \, mL + 30 \, mL = 50 \, mL$.Normality of the resulting solution = $\frac{	ext{Excess equivalents}}{	ext{Total volume}} = \frac{1 \, meq}{50 \, mL} = 0.02 \, N$.Therefore,the solution is $0.02 \, N$ basic.

When $20 \, mL$ of $0.25 \, N$ strong acid and $30 \, mL$ of $0.2 \, N$ strong base are mixed,the resulting solution will be.......
