Question

when copper sulphate is stirred into water the water turns blue. what 2 tests could you carry our to see whether this mixture is a suspension or solution ​

Answer 1

Answer:

when a compound dissolves in water, it dissociates to form ions. The reaction between anhydrous copper(II) sulfate and water is used as a test for water. The white solid turns blue in the presence of water. The backward reaction is exothermic - energy is transferred to the surroundings when it happens.
