reversible reactions and equibrilia

what is a reversible reaction

a reaction that when products can go to reactant and reactants can go to products

⇌ this is the symbol

how would you investigate this reversible reaction with hydrate copper sulphate

using hydrated copper sulphate turning into anhydrous copper sulphate + water

you need to heat the hydrated copper sulphate, it will turn from a blue crystal to a white powder.

Then when you add water, it becomes hydrated copper sulphate again.

how would you investigate this reversible reaction with ammonium chloride

when you heat ammonium chloride, a colourless gas is produced.

In the cooler parts of the test tube with the ammonium chloride will form the white solid, this solid is the ammonium chloride.
