10 mL citric acid $(H_{3} C_{6} H_{5} O_{7})$ is neutralised completely by 35.6 mL of 0.312 M NaOH solution. The molarity of the solution of citric acid is

Options:

Answer:

Solution:

$H_{3} C_{6} H_{5} O_{7} + 3 N a O H \to N a_{3} C_{6} H_{5} O_{7} + 3 H_{2} O$
$\frac{M_{1} V_{1}}{1} = \frac{M_{2} V_{2}}{3}$ or $M_{1} = \frac{M_{2} V_{2}}{3 V_{1}}$
$= \frac{0.312 \times 35.6}{3 \times 10} = 0.37 M$
