Question
Identify the incorrect statement
A.
$$CuS{O_4}$$ reacts with $$KCl$$ in aqueous solution to give $$CuC{l_2}.$$
B.
$$CuS{O_4}$$ reacts with $$KI$$ in aqueous solution to give $$C{u_2}{I_2}.$$
C.
$$CuS{O_4}$$ react with $$NaOH$$ and glucose in aqueous medium to give $$C{u_2}O.$$
D.
$$CuS{O_4}$$ on strong heating gives $$CuO.$$
Answer :
$$CuS{O_4}$$ reacts with $$KCl$$ in aqueous solution to give $$CuC{l_2}.$$
Solution :
$$2CuS{O_4} + 4KI \to C{u_2}{I_2} + 2{K_2}S{O_4} + {I_2}$$
( not given by $$KCl$$ ).
Fehling solution gives $$C{u_2}O$$ with reducing substances
\[CuS{{O}_{4}}\xrightarrow[\Delta ]{\text{strong}}CuO+S{{O}_{3}}\]
