Question

WhIch of the following ls less soluble in water

Options
  • A

    Be(OH)2

  • B

    Mg(OH)2

  • C

    Ca(OH)2

  • D

    Sr(OH)2

Explanation

Beryllium hydroxide is the least soluble among the alkaline earth metal hydroxides. It has low solubility in water and tends to form a gelatinous precipitate. This is because beryllium is a small and highly charged cation, and the hydroxide ions have difficulty solvating it

Magnesium hydroxide is more soluble than beryllium hydroxide but less soluble than calcium and strontium hydroxides. It is sparingly soluble in water and forms a suspension, which is a common over-the-counter antacid.

Calcium hydroxide is more soluble than beryllium and magnesium hydroxides. It is moderately soluble in water and forms a saturated solution known as "lime water." Lime water is commonly used in laboratory experiments and various applications

Strontium hydroxide is the most soluble among these hydroxides. It is readily soluble in water and forms a clear solution. Strontium hydroxide is used in some chemical applications and in the production of color television
