The water having more dissolved $\mathrm{O}_{2}$ is
1 Boiling water
2 Water at $80^{\circ} \mathrm{C}$
3 Polluted water
4 Water at $4^{\circ} \mathrm{C}$
Explanation:
Dissolved oxygen means amount of Oxygen that is present in water. Cold water has the possibility to hold more dissolved oxygen in comparison of warm water. So, the water having more dissolved $\mathrm{O}_{2}$ is water at $4^{\circ} \mathrm{C}$.

Out of $\mathrm{BeF}_{2}, \mathrm{MgF}_{2}, \mathrm{CaF}_{2}, \mathrm{SrF}_{2}$ which has maximum solubility:
1 $\mathrm{BeF}_{2}$
2 $\mathrm{MgF}_{2}$
3 $\mathrm{CaF}_{2}$
4 $\mathrm{SrF}_{2}$
Explanation:
Among the all options $\mathrm{BeF}_{2} \rightarrow \mathrm{Be}^{2+}$ have high hydration energy so $\mathrm{BeF}_{2}$ has maximum solubility.

Which of the following is most soluble in water?
1 $\mathrm{CsClO}_{4}$
2 $\mathrm{NaClO}_{4}$
3 $\mathrm{KClO}_{4}$
4 $\mathrm{LiClO}_{4}$
Explanation:
The high solubility of $\mathrm{LiClO}_{4}$ is mainly due to high heat of hydration of $\mathrm{Li}^{+}$ion.

Which of the following alcohol has highest solubility in water?
1 Secondary butyl alcohol
2 Tertiary butyl alcohol
3 Ethelene glycol
4 Glycerol
Explanation:
Among the all options only glycerol has more number of hydroxyl groups so, glycerol has tendency to form hydrogen bond with water. So we can say glycerol has highest solubility in water.
