What is the molarity of an HCl solution if 43.6 mL of a 0.125 M NaOH solution are needed to titrate a 25.0 mL sample of the acid
Sveta_85 [38]

Answer: The molarity of an HCl solution is 0.218 M if 43.6 mL of a 0.125 M NaOH solution are needed to titrate a 25.0 mL sample of the acid.

Explanation:

Given: V_{1} = 43.6 mL,      M_{1} = 0.125 M

V_{2} = 25.0 mL,        M_{2} = ?

Formula used to calculate the concentration of acid is as follows.

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

Substitute the values into above formula.

M_{1}V_{1} = M_{2}V_{2}\\0.125 M \times 43.6 mL = M_{2} \times 25.0 mL\\M_{2} = 0.218 M

Thus, we can conclude that the molarity of an HCl solution is 0.218 M if 43.6 mL of a 0.125 M NaOH solution are needed to titrate a 25.0 mL sample of the acid.
