BOTH STATEMENT CORRECT AND CORRECT REASON
BUT HOW DOES REASON EXPLAIN STATEMENT?
@ABCDMA-ABCDMA Copper ion solutions. Solution of copper II ions (Cu2-) in copper sulphate . When concentrated hydrochloric acid (HCl) is added, tetrachlorocuprate II complex ions ((CuCl4)2-) are formed. These ions are yellow in colour, which with the blue colour of copper ions results in a vivid green coloured solution .
[Cu(H2O)4]2+ is pale blue in colour so the resulting solution is green in colour ....hence the reason is the correct explanation of assertion
