Answer 2

When CuSO4 is tested on pH paper, then the color observation should be​ Orange or Yellow.

- To test CuSO4 on pH paper, we have to make an aqueous solution of it.

- This solution is acidic in nature with a pH of about 4.5 - 4.6.

- So, when this solution is tested on a pH paper, the color change observed will be orange or yellowish.
