Question

H3PO4+3NaOH=.......+.........3​

Answer 1

H3PO4+3NaOH=Na3PO4+3H2O

Answer 2

The chemical equation you've provided is the reaction between phosphoric acid (H3PO4) and sodium hydroxide (NaOH) to produce a salt and water. This is a neutralization reaction. Here's the balanced equation:

H3PO4 + 3NaOH -> Na3PO4 + 3H2O

In this reaction, one molecule of phosphoric acid (H3PO4) reacts with three molecules of sodium hydroxide (NaOH) to produce one molecule of sodium phosphate (Na3PO4) and three molecules of water (H2O).
