How do you make salt crystals in a lab?

Showing 1 to 5 of 5

Basically, the questions in the title. My teacher told me that there are 4 main ways (if that helps!)
Thanks x :)

Well we mixed salt with water and then put it in a burning dish thing and then put it over a bunsen burner and let it boil and then left it for about 1 week and there was crystals left in the dish i hope that helps!

sorry, not quite...
I think it was something like
metals + acids --> salt + water
I think there was three others...
thanks anyway. :)

acid + metal --> salt + hydrogen

acid + base (metaloxides or metal hydroxides) --> salt + water

acid + carbonates --> salt + water + carbondioxide

does this help ?
