Note: Some versions of naalo2 are written as: na[al(oh)4]; If the product has gas and the reactant has no gas, it should be marked with a gas mark.

The ion equation is also very easy to rewrite, it should be noted that insoluble substances such as Al2O3, Al, and gas cannot be disassembled into ionic form.
