229368 The ionic product of water with increase in temperature.

229383 Why only $\mathrm{As}^{3+}$ gets precipitated as $\mathrm{As}_2 \mathrm{~S}_3$ and not $\mathrm{Zn}^{2+}$ as $\mathrm{ZnS}$ when $\mathrm{H}_2 \mathrm{~S}$ is passed through an acidic solution containing $\mathrm{As}^{3+}$ and $\mathrm{Zn}^{2+}$ ?

229419 Which of the following inert gas is soluble in water?

229447 An aqueous solution contains $\mathrm{Ni}^{2+}, \mathrm{Co}^{2+}$ and $\mathrm{Pb}^{2+}$ ions at equal concentrations. The solubility product of $\mathrm{NiS}, \mathrm{PbS}$ and $\mathrm{CoS}$ in water at $25^{\circ} \mathrm{C}$ are $1.4 \times 10^{-24}, 3.4 \times 10^{-28}$ and $3 \times 10^{-26}$ respectively. Indicate which of these ions will be precipitated first and last when sulphide concentration is progressively increased from zero.
