Magnesium hydroxide is classified as which in water?

Explanation:
Solubility in water is the idea being tested. Magnesium hydroxide dissolves only very slightly in water, so it isn’t considered soluble. Most of it stays as a solid, which is why you often see a cloudy suspension called milk of magnesia rather than a clear solution. It doesn’t react with water under ordinary conditions, and it only decomposes when heated, not just in water. So the best description is insoluble in water.
