What is the net ionic equation of the reaction of MgCl2 with NaOH?

In many chemical reactions of two or more compounds, ions are present in the solution that do not participate in the reaction. These ions, known as spectator ions, can be removed from the chemical equation describing the reaction. A chemical equation that has the spectator ions removed is known as a net ionic equation.

Reactions between ionic compounds often result in the precipitation of an insoluble compound. Spectator ions and precipitation products of a chemical reaction can be predicted by consulting
an ionic substance solubility table. Here is one such table:

When entering chemical equations, please follow the following formatting guidelines

  • Add phases to all chemical reactions unless asked otherwise. When adding phases, make sure not to place them as a subscript.
  • Do not stack charges and subscripts. To add a charge to an ion with a subscript, first enter the subscript. For example, to type SO42− start by typing SO4. Then use the arrow key to arrow over before adding a superscript with the charge.
