Question
Which formula shown is incorrect for the name given?Group of answer choicesmagnesium nitrite: Mg(NO2)3calcium carbonate: CaCO3aluminum sulfate: Al2(SO4)3sodium hydrogen carbonate: NaHCO3potassium hydroxide: KOH
Solution
The incorrect formula for the name given is magnesium nitrite: Mg(NO2)3. The correct formula for magnesium nitrite is Mg(NO2)2. This is because magnesium has a +2 charge and nitrite (NO2) has a -1 charge. In order to balance the charges, there should be two nitrite ions for each magnesium ion, hence the formula should be Mg(NO2)2.
