A volume of 100mL of a 0.800 M HNO3 solution is titrated with 0.640 M KOH. Calculate the volume of KOH required to reach the equivalence point.
HNO3 + KOH ==> KNO3 + H2O
How many moles do you have? That's M x L HNO3. Look at the coefficients in the balanced equation. 1 mol HNO3 = 1 mol KOH; therefore, mols HNO3 = moles KOH.
M KOH = moles KOH/L KOH. You know M KOH and mols KOH; solve for L KOH.
