Sample ChemFiesta Stoichiometry Lab Question and Answer

Question

A student performs a titration to determine the concentration of an unknown hydrochloric acid (HCl) solution. They use 25.0 mL of HCl and titrate it with 0.100 M sodium hydroxide (NaOH). The titration requires 30.0 mL of NaOH to reach the endpoint. What is the concentration of the HCl solution?

Step-by-Step Solution

Step 1: Write the balanced chemical equation

HCl + NaOH → NaCl + H₂O

The equation is already balanced.

Step 2: Calculate moles of NaOH used

• Molarity (M) = moles/volume (L)
• Moles NaOH = 0.100 mol/L × 0.030 L = 0.003 mol

Step 3: Use mole ratio to find moles of HCl

• From the balanced equation, the mole ratio of HCl to NaOH is 1:1.
• Moles HCl = Moles NaOH = 0.003 mol

Step 4: Calculate concentration of HCl

• Volume of HCl solution = 25.0 mL = 0.025 L
• Concentration = moles/volume = 0.003 mol / 0.025 L = 0.12 M

Answer: The concentration of the HCl solution is 0.12 M.
