I have been provided with 250.00 cm³ of limewater which has been made such that it contains approximately 1g dm¯³ of calcium hydroxide. Also available is hydrochloric acid which has a concentration of exactly 2.00 mol dm¯³. This acid is too concentrated to be used at full strength, so it will need to be diluted to a suitable strength that will allow us to get a good degree of accuracy without diluting it too far or using too much. I must also use an appropriate quantity of limewater to work out the exact concentration of the hydrochloric acid. I have chosen to use 30.00cm³ because it is a large enough amount to give a good degree of accuracy when neutralising it, and will also...
