Is Ca soluble or insoluble ?
- Trevor HLv 79 years agoFavorite Answer
Ca is a metal which is insoluble in water. However , calcium metal reacts with water, evolving hydrogen gas at a rate rapid enough to be noticeable, but not fast enough at room temperature to generate much heat.
The reaction equation is:
Ca(s) + 2H2O (l) → Ca(OH)2(s) + H2(g)
Part of the slowness of the calcium-water reaction results from the metal being partly protected by insoluble white calcium hydroxide.
So calcium metal does not dissolve in water , but it will react with water to generate hydrogen and to produce the sparingly soluble hydroxide Ca(OH)2 . The Ca(OH)2 "solution " is basic . In chemistry this is called lime water.

No.Calcium is a metal. But it can form soluble salts.

Calcium DISSOLVES very nicely in anhydrous liquid ammonia.

usually no, but it depends with what Ca is bonded with.
