- OH HBrarrow_forwardWhich of the following best describes why magnesium hydroxide, found in milk of magnesia, is soluble in acidic solution? O According to Le Chatelier's principle, the acid will react with hydroxide ions in the solution, forming water and thereby decreasing the concentration of hydroxide ions in solution causing more magnesium hydroxide to dissolve. O Magnesium hydroxide does not dissolve in acidic solutions. O According to Le Chatelier's principle, the acid will react with magnesium ions in the solution, forming magnesium hydride and causing more magnesium hydroxide to dissolve.
