To determine the concentration of a lime water solution
Definition
- My task is to plan an experiment to find the accurate concentration of the limewater solution which is roughly 1gdm-3.
- To do this I am going to do a titration using hydrochloric acid which I will need to dilute
- I am provided with 250cm3 of limewater, 2.00mldm-3 of Hydrochloric acid and an indicator
- I hypothesise that if I double the concentration of acid then the amount required to neutralise the calcium hydroxide will decrease by two because it is well know that if you double the concentration of something you will only need half the amount to have the same effect.
