H2SO4(aq) + NaOH(aq)-> Na2SO4(aq) + H2O(l)

Question

Consider the unbalanced equation above. What is the concentration of the original sulfuric acid solution if 60.5 mL of the acid reacts with 18.0 mL of 0.110 M sodium hydroxide?

Answer 1

1. Balance the equation.
2. mols NaOH = M x L = ?
3. Convert mols NaOH to mols H2SO4.
4. M H2SO4 = moles H2SO4/L H2SO4.
