don't know do u know sorry mark

Answer 2

Answer:

magnesium hydroxide is also known as milk of magnesia .which is used in medication of antacids .

it is obtained by Combining a solution of many magnesium salts with alkaline water induces precipitation of solid Mg(OH)2:

Mg2+ + 2 OH− → Mg(OH)2

On a commercial scale, Mg(OH)2 is produced by treating seawater with lime (Ca(OH)2). Ca(OH)2 is far more soluble than Mg(OH)2, so the latter precipitates as a solid

{MgO + H2O -------> Mg(OH)2}
