What do you know about zinc, what do you know about sodium sulphate.

Please read forum rules.

Isn't NaSO₄, sodium sulphate?

[tyana21]

pardon me,i overlooked that part of the rules.well,zinc is not soluble in water and sodium sulphate is.so is it advisable to use crystallisation?

[Arkcon]

Oh, yes, next time, put the question in the post, instead of the title.  it helps us keep track.  I am 2 for 2 today with giving bad advice.  Srry.

Try to outline whole procedure you will use. Crystallization is an important part of it

BTW: sodium sulfate is Na₂SO₄.

thanks Borek and
firstly issit correct if i mix the mixture with water then filter and lastly crystallise?
or am i missing something out?

[Arkcon]

That's a good general outline.  Try to be more specific, a step by step procedure, so you can hand in something clear, and with correct spelling and punctuation for the teacher tomorrow.  Crystallise may be acceptable depending on where you are, but issit might not.
