Crystals of copper sulphate are heated in a test tube for some time. i. What is the colour of copper sulphate crystals a. before heating, and b. after heating? ii. which one of these has a higher concentration of H + ions?1 M HCL or 1M CH 3 COOH

Question

Philoid · Accepted Answer

i. a. blue (due to the water of crystallisation)

b. white (due to the loss of water of crystallisation after heating)

ii. 1 M HCl has a higher concentration of H⁺ ions as HCl is a stronger acid compared to CH₃COOH.

(Reason: A strong acid produces more H⁺ ions on ionisation than a weak acid. Here HCl is a strong acid compared to CH₃COOH).
