Solution

The correct option is B False
Lime water turns milky on passing $C O_{2}$ gas.
Reaction is:
$C a (O H)_{2} + C O_{2} \to C a C O_{3} (m i l k i n e s s) + H_{2} O$

$C a C O_{3} e x c e s s o f C O_{2} - ------- \to C a (H C O_{3})_{2} (s o l u b l e)$

Hence, the given statement is $f a l s e$
