Chapter 10: Q.10.51 (page 350)

What is the molarity of a solution of HCL if 5ml of the HCL solution is titrated with 28.6ml of a 0.145 M NaOH solution?
$HCl (a q) + NaOH (a q) ⟶ H_{2} O (l) + NaCl (a q)$

Short Answer

Expert verified

The molarity of a solution of HCL is $0.829$ M.

Step by step solution

Given information

Molarity is a proportion of the concentration of a chemical species, in particular of a solute in a solution, as far as the measure of substance per unit volume of solution.

Explanation

We have, $5$ ml of the HCL solution is titrated with $28.6$ ml of a $0.145$ M NaOH solution.

$HCl (a q) + NaOH (a q) ⟶ H_{2} O (l) + NaCl (a q)$

We know, $1 LNaOH = 0.145 molNaOH$

Also, $1 molNaOH = 1 molHCl$

Calculating the molarity,

$28.6 mLNaOH \times \frac{1 L}{1000 mL} \times \frac{0.145 molNaOH}{1 LNaOH} \times \frac{1 molHCl}{1 molNaOH} = 0.00415 mol$

Now,

$\frac{0.00415 molHCl}{(\frac{5 m L}{1000 mL})} = 0.829 M$

Hence the molarity of a solution of HCL is $0.829 M$
