MCQ
Which of the following has max. solubility at low $pH$?
- A$NH _{4} Cl$
- B$NaCl$
- C$Na _{3} PO _{4}$
- ✓$\operatorname{Sr}( OH )_{2}$
✓
Answer
Correct option: D.
$\operatorname{Sr}( OH )_{2}$
d
The compound, $Sr $$( OH )_{2}$, has max. solubilityin acidic solution that is at low $pH$ as shown below.
The compound, $Sr $$( OH )_{2}$, has max. solubilityin acidic solution that is at low $pH$ as shown below.
$Sr ( OH )_{2} \rightarrow Sr ^{+}+2 OH ^{-}$
It gives high amount of hydroxide ions which are neutralized by the high amount of $H ^{+}$ ions.
