Solution

The correct option is B 0.5 M
$M_{1} V_{1} = M_{2} V_{2}$

$M_{1} =$ Required NaOH concentration
$V_{1} =$ 20 mL
$M_{2} = 1$ M = concentration of HCl
$V_{2} =$ 10 mL = volume of HCl solution

$M_{1} V_{1} = M_{2} V_{2}$

$M_{1} \times 20 = 1 \times 10$

$M_{1} = 0.5 M$

The correct option is B 0.5 M
$M_{1} V_{1} = M_{2} V_{2}$

$M_{1} =$ Required NaOH concentration
$V_{1} =$ 20 mL
$M_{2} = 1$ M = concentration of HCl
$V_{2} =$ 10 mL = volume of HCl solution

$M_{1} V_{1} = M_{2} V_{2}$

$M_{1} \times 20 = 1 \times 10$
