Write down the equation sodium hydroxide + copper (II) chloride = copper (II) hydroxide + sodium chloride.

A chemical reaction takes place between substances such as sodium hydroxide and bivalent copper chloride salt. As a result of the passage of a chemical reaction, the following substances are formed: bivalent copper hydroxide and sodium chloride salt (table salt). This reaction takes place as an exchange. In order for the equation of the chemical reaction to be equalized, we need to put the number 2 in front of the sodium hydroxide and in the reaction products put the number 2 in front of the salt with sodium chloride. The molecular equation of the reaction can be written as follows:
2 NaOH + CuCl2 = Cu (OH) 2 + 2 NaCl.
