Question

9 multiple choice 10 points what is the iupac name of the base mg(oh)₂? magnesium hydroxide magnesium oxyhydride hydromagnesium base magnesium dihydroxide

Explanation:

According to the IUPAC naming rules for inorganic compounds, for ionic compounds like \(Mg(OH)_2\), the cation (magnesium ion, \(Mg^{2+}\)) is named first, followed by the anion (hydroxide ion, \(OH^-\)). Since there is no need to indicate the number of hydroxide ions in the simple IUPAC naming of common bases (as the charge of the cation \(Mg^{2+}\) and the charge of the hydroxide ion \(OH^-\) (\(- 1\)) already imply a \(1:2\) ratio), it is named magnesium hydroxide.

Answer:

A. Magnesium hydroxide
