Write down the equations for obtaining a sodium aluminate solution based on aluminum chloride.

In order to carry out a chemical reaction, we need to take the aluminum chloride salt and sodium hydroxide base. As a result of chemical interaction, aluminum hydroxide and sodium chloride salt are formed. In order to equalize the reaction, we need to put the number 3 in front of the sodium chloride salt. The molecular equation of the reaction can be written as follows:

AlCl3 + 3 NaOH = Al (OH) 3 ↓ + 3 NaCl

The ionic reaction equation can be written as follows:

Al ³⁺ + 3 Cl ^– + 3 Na ⁺ + OH ^–  = Al(OH)₃↓ + 3 Na ⁺ + 3 Cl ^–

The abbreviated ionic equation can be written as follows:

Al ³⁺ + OH ^–  = Al(OH)₃↓ .
