Equation for Mg(NO3)2 + H2O (Magnesium nitrate + Water)

In this video we will describe the equation Mg(NO3)2 + H2O and write what happens when Mg(NO3)2 is dissolved in water.

When Mg(NO3)2 is dissolved in H2O (water) it will dissociate (dissolve) into Mg 2 and 2NO3- ions. To show that they are dissolved in water we can write (aq) after each. The (aq) shows that they are aqueous – dissolved in water.

The equation for Mg(NO3)2 (Magnesium nitrate) and H2O sometimes isn’t considered a chemical reaction since it is easy to change the Mg +2 and 2NO3- back to Mg(NO3)2 (just let the H2O evaporate). At the same time, the Mg(NO3)2 is a very different substance than Mg2+ and 2NO3-.
