HCl with Na 2 CO 3 Eq. of HCl =E q. of Na 2 CO 3 E q of HCl =E q. of NaOH (6/25) × 1 × (V/1000)=(30/1000) × 0.2 × 1 V=25 ml

Q. $25 m l$ of the given $H Cl$ solution requires $30 m L$ of $0.1 M$ sodium carbonate solution. What is the volume of this $H Cl$ solution required to titrate $30 m L$ of $0.2 M$ aqueous $N a O H$ solution?

25 mL

50 mL

12.5 mL

75 mL

$H Cl$ with $N a_{2} C O_{3}$
Eq. of $H Cl = Eq$ . of $N a_{2} C O_{3}$
$Eq$ of $H Cl = Eq$ . of $N a O H$
$\frac{6}{25} \times 1 \times \frac{V}{1000} = \frac{30}{1000} \times 0.2 \times 1$
$V = 25 m l$
