5 ml of N HCl, 20 ml of $N / 2 H_{2} S O_{4}$ and 30 ml of $N / 3 H N O_{3}$ are mixed together and volume made to one litre. The normality of the resulting solution is

Q. 25 mL of water is added to 100 mL of a decinormal

H C l

solution. Calculate the normality of the resultant mixture.

Q. 22.7 ml of N/10

N a_{2} C O_{3}

solution neutralizes 10.2 ml of a dilute

H_{2} S O_{4}

. Then the volume of water that must be added to 400 ml of same

A dilute solution of H2SO4 is made by adding 5 mL of 3N H2SO4 to 245 mL of water. The normality and molarity of the solution is:

The correct option is B 0.06 N and 0.03 MNormality=5(3)5+245=0.06Normality=molarity×nfactor⟹0,06=M×2M=0.03

A dilute solution of $H_{2} S O_{4}$ is made by adding 5 mL of 3N $H_{2} S O_{4}$ to 245 mL of water. The normality and molarity of the solution is:

The correct option is B 0.06 N and 0.03 M
$N o r m a l i t y = \frac{5 (3)}{5 + 245} = 0.06$

$N o r m a l i t y = m o l a r i t y \times n f a c t o r$

$⟹ 0, 06 = M \times 2$

$M = 0.03$
