10 ml of concentrated HCl were diluted to 1 litre. 20 ml of this diluted solution required 25 ml of 0.1 N sodium hydroxide solution for complete neutralization, the normality of the concentrated acid will beA. 8B. 9.5C. 12.5D. 15 |

Answer» Correct Answer - C `{:(HCl,NaOH),(N_(1)V_(1)=,N_(2)V_(2)):}` `N_(1)xx20ml=0.1xx25impliesN_(1)=(0.1xx25)/(20)=0.125` If one litre HCl present in 0.125 Therefore in 10 ml `=(0.125)/(1000)xx100=12.5` The normality of conc. `HCl` is 12.5 N. |
