    The normality and volume strength of a solution made by mixing 1.0 L each of 5.6 volume and 11.2 volume \[{{H}_{2}}{{O}_{2}}\] solution are:

    A) 1 N, 5.6 vol     

    B) 1.5 N, 5.6 vol

    C) 1.5 N, 8.4 vol                

    D) 1 N, 8.4 vol

    Correct Answer: C

    Solution :

    [c] \[1\,N=5.6vol\] \[\Rightarrow \] Normalities of two solutions are 1 N and 2N Normality of mixture \[=\frac{1\times 1+1\times 2}{1+1}=\frac{3}{2}=1.5N\] Volume strength \[=\frac{3}{2}\times 5.6=\frac{16.8}{2}=8.4\,Vol\]
