steps of salt preparation

Question 1

precipitation

Answer 1

1. Mix both solutions together, with one added in excess.
2. Filter the mixture and collect the residue, which is the insoluble salt formed as a precipitate.
3. Wash and dry the salt.

Question 2

titration

Answer 2

1. Titrate the ____ solution with the dilute ____ acid using screened methyl orange until it just changes to grey.
2. Repeat the experiment without the indicator to obtain a pure salt solution.
3. Heat the solution till saturated and allow it to cool for the crystals to form.
4. Dry the crystals to obtain pure and dry crystals.

Question 3

solid-acid reaction

Answer 3

1. Add excess insoluble carbonate/base/metal into dilute ____ acid and stir.
2. Filter the mixture to remove the excess, unreacted solids. The filtrate is the ____ solution.
3. Heat the solution gently till saturated and allow it to cool for the crystals to form.
4. Filter the mixture to collect the crystals, then dry them to obtain pure and dry crystals.
