A group 14 element is oxidised to form corresponding oxide which is gaseous in nature, when dissolved in water $$pH$$ of the water decreases further addition of group 2 hydroxides leads to precipitation. This oxide can be
A.
$$Ge{O_2}$$
B.
$$CO$$
C.
$$C{O_2}$$
D.
$$Sn{O_2}$$
Answer :
$$C{O_2}$$
Solution :
$$C{O_2}$$ forms carbonic acid $${H_2}C{O_3},$$ when dissolved in water, $$CO$$ is neutral, whereas other two $$Ge{O_2}$$ and $$Sn{O_2}$$ are solids.
