Chemistry – The Periodic Table - Group I properties | e-Consult

Based on the reaction of sodium hydroxide with hydrochloric acid, we can predict the following properties for lithium hydroxide and strontium hydroxide:

• Lithium Hydroxide (LiOH): Lithium hydroxide is expected to be soluble in water and will react with hydrochloric acid to produce lithium chloride and water. It will be less soluble and less reactive than sodium hydroxide.
• Strontium Hydroxide (Sr(OH)₂): Strontium hydroxide is expected to be soluble in water and will react with hydrochloric acid to produce strontium chloride and water. It will be less soluble and less reactive than sodium hydroxide. Strontium hydroxide is also expected to be less soluble than lithium hydroxide.

Prediction of Solubility and Reactivity: As you move down Group I, the solubility of the hydroxides generally increases. The reactivity with acids will also increase, although strontium hydroxide will be less reactive than sodium hydroxide due to the increasing ionic size and decreasing charge density of the cations.
