If an aqueous solution of sulfuric acid (H2SO4) is neutralized by 3.20 mol of sodium hydroxide (NaOH), how many moles of acid were originally present in the solution?
If completely neutralized, the balanced equation is
2NaOH + H2SO4 ==> Na2SO4 + 2H2O
The equation tell you that 2 moles NaOH = 1 mole H2SO4 so 3.2 moles NaOH must equal ?? moles H2SO4.
