When $40mL$ of $0.1NHCl$ and $20mL$ of $0.1M{H}_{2}S{O}_4$ are mixed together, the normality of the mixture will be:

Q. $100ml$ of $0.1M{H}_{2}S{O}_4$ and $100ml$ of 0.1M KOH are mixed together and diluted to exactly two litres. Normality of unreacted acid in the mixture is:

Q. $5mL$ of $NHCl,20mL$ of $N/2H_{2}S{O}_4$ and $30mL$ of $N/3HN{O}_3$ are mixed together and volume made to $1L$.

Q. A 20 ml solution of 0.2 N $N{a}_{2}C{O}_3$ is titrated with 0.1 N $HCl$ with phenolphthalein as the indicator. Another 20 ml solution of 0.2 N $N{a}_{2}C{O}_3$ is titrated with 0.1 N $HCl$ with methyl orange as the indicator. The volume of $HCl$ required for both the titrations resepectively is:

Q. $5$ mL of $1N$ HCl, $20$ mL of $\frac{N}{2}$ $H_{2}S{O}_4$ and $30$ mL of $\frac{N}{3}HN{O}_3$ are mixed together and the volume is made to $1$L. The normality of the resulting solution is:

Q. Which of the following will give 60 ml of 0.4 M NaOH solution?
