Out of the given salts, [tex]C e_{2}\left(S o_{4}\right)_{3} [/tex] decreases in solubility as the temperature increases.
Answer: Option B
Explanation:
Here we are talking about Cerium (III) Sulphate which is an inorganic compound, commonly known as Cerous Sulphate. Its chemical formula is [tex]C e_{2}\left(S o_{4}\right)_{3}[/tex]. This salt has a monoclinic crystal structure and appears off-white in colour.
It’s solubility in water is 9.25 g/100ml at the temperature of 20[tex]^{\circ} \mathrm{C}[/tex], that decreases with the increase in temperature and that’s why it’s counted amongst those few salts that has less solubility when increase temperature.
