Write down the equation of the chemical reaction: phosphoric acid + sodium hydroxide sodium phosphate + water.

Phosphoric acid react with sodium hydroxide. As a result of the reaction, sodium phosphate is formed and water is released. The reaction proceeds according to the type of substitution. The chemical equation for the reaction is as follows:

2 H3PO4 + 6 NaOH = 2 Na3PO4 + 6 H2O.

We set the coefficients, set 2 in front of phosphoric acid, set 6 in front of sodium hydroxide, and similarly in the reaction products, set 2 in front of sodium phosphate and set 6 in front of water, thereby completely equalizing the reaction.
