Question: Identify the incorrect statement
Options:
A) $ CuSO_4 $ reacts with $ KCl $ in aqueous solution to give $ Cu_2Cl_2 $ .
B) $ CuSO_4 $ reacts with KI in aqueous solution to give $ Cu_2I_2 $ .
C) $ CuSO_4 $ react with $ NaOH $ and glucose in aqueous medium to give $ Cu_2O $ .

Show Answer
Answer:
Correct Answer: A
Solution:
$ 2CuSO_4+4KI\to Cu_2I_2+2K_2SO_4+I_2 $ (not given by KCl).
Fehling solution gives $ Cu_2O $ with reducing substances $ CuSO_4\xrightarrow[\Delta ]{strong}CuO+SO_3 $
