    Help with experiment Jack_6934

    I did evaporation saying to boil the water to remove the hard water and purify it and I mentioned ion exchange and said to mix sodium and calcium ions. Even though I wrote mostly on evaporation, will i get any marks? Like attempt marks and mentioning ion exchange.

      My science teacher said the right answer is distillation! But I did evaporation too and he told me I will definitely get 3/4 of the marks as its nearly right, just the water won't be left or soemthing :)
