    75 c.c. of \[N\text{/}5\]\[{{H}_{2}}S{{O}_{4}}\]10 c.c. of \[N\text{/}2\,\]\[HCl\] and 30 c.c. of \[N\text{/}10\] \[HN{{O}_{3}}\] are mixed together. The strength of the resulting acid mixture is:

    A)  0.1 N                    

    B)         0.2 N    

    C)         0.3 N                    

    D)         0.4 N

    Correct Answer: B

    Solution :

                                                    Normality of the resulting mixture \[=\frac{{{N}_{1}}{{V}_{1}}+{{N}_{2}}{{V}_{2}}+{{N}_{3}}{{V}_{3}}}{{{V}_{1}}+{{V}_{2}}+{{V}_{3}}}\] \[=\frac{75\times \frac{1}{5}+10\times \frac{1}{2}+30\times \frac{1}{10}}{75+10+30}\] \[=\frac{15+5+3}{115}\] \[=\frac{23}{115}=\frac{N}{5}=0.2N\]
