1.	5 mL of N HCl, 20 mL of N/2 H_(2)SO_(4) and 30 mL of N/3HNO_(3) are mixed together and volume made to 1L. The normality of resulting solution is
Answer» 0.45 0.025 0.9 0.05 Solution :Normally EQUTAION is `N_(1)V_(1)+N_(2)V_(2)+N_(3)V_(3)=N_(4)(V_(1)+V_(2)+V_(3))` or `1xx5+20xx(1)/(2)+30xx(1)/(3)=N_(4)(5+20+30)` `(HCI) (H_(2)SO_(4)) (HNO_(3))` `therefore` Resulting normality `(N_(4))=(25)/(55)=0.45N`.
