Question

Which is false for the following reaction?
$\underset{A}{{\left[Cu{\left(H_{2}O\right)}_{3}OH\right]}^{+}}+\underset{B}{{\left[Al{\left(H_{2}O\right)}_6\right]}^{3+}}⟶\underset{C}{{\left[Cu{\left(H_{2}O\right)}_4\right]}^{2+}}+\underset{D}{{\left[Al{\left(H_{2}O\right)}_{5}OH\right]}^{2+}}$

• A. $A$ is base and $B$ is acid
• B. $C$ is conjugate acid of $A$
• C. $B$ is conjugate acid of $D$
• D. $B$ is conjugate base of $D$

Answer 1

Answer: (A), (B), (C)

The correct options are
A $A$ is base and $B$ is acid
B $C$ is conjugate acid of $A$
C $B$ is conjugate acid of $D$

Here, $A$ is gaining $H^{+}$ and $B$ is losing $H^{+}$.

So, $C$ is the conjugate acid of $A$ and $D$ is the conjugate base of $B$ and vice-versa.

Hence, option (A), (B), (C) is correct.
