Calculate the concentration of hydrochloric acid if 50.0 mL of hydrochloric acid is neutralized by 25.0 mL of 2.0 M sodium hydro

Arisa [49]

Answer:

1.0M HCl is the concentration of the acid

Explanation:

Based on the reaction, 1 mole of NaOH reacts per mole of HCl. That means the moles added of NaOH in the neutralization = Moles of HCl in the solution. With the moles and the volume in Liters we can find the molar concentration of HCl

<em>Moles NaOH = Moles HCl:</em>

25.0mL = 0.025L * (2.0moles / L) = 0.050moles HCl

<em>Molarity:</em>

0.050moles HCl / 0.0500L =

<h3>1.0M HCl is the concentration of the acid</h3>
