This is too much, so it would be better to have the HCl twice as concentrated as the limewater, say 0.02 mol/dm3. This would give similar volumes for the acid and the alkali in the titration. To make a 0.020 mol/dm3 HCl solution from your 2.00 mol/dm3 solution you would have to dilute it by a factor of 100. To do this...
