Finish the equations of ion exchange reactions in molecular form, draw up the complete and abbreviated ionic equations: Phosphoric acid + sodium hydroxide = Iron (III) nitrate + sodium hydroxide =

The proposed reactions are related to exchange reactions.

An exchange reaction is a reaction between two complex substances, as a result of which they exchange their constituent parts.

The exchange reaction proceeds to the end if: water, gas is formed, or one of the substances precipitates out.

H3PO4 + 3NaOH = Na3PO4 + 3H2O – water is formed.

3H ^ (+) + PO4 ^ (3-) + 3Na ^ (+) + 3OH ^ (-) = 3Na ^ (+) + PO4 ^ (3-) + 3H2O

3H ^ (+) + 3OH ^ (-) = 3H2O

Fe (NO3) 3 + 3NaOH = Fe (OH) 3 + 3NaNO3- a precipitate is formed.

Fe ^ (3+) + 3NO3 ^ (-) + 3Na ^ (+) + 3OH ^ (-) = Fe (OH) 3 + 3Na ^ (+) + 3NO3 ^ (-)

Fe ^ (3+) + 3OH ^ (-) = Fe (OH) 3
