What is the reaction when adding HCl to sodium bicarbonate? Then adding in sodium hydroxide creates a precipitation.
Question Date: 2016-10-12
Answer 1:

HCl + HNaCO3 -> NaCl + H2CO3 <-> NaCl + H2O + CO2

The reaction bubbles over because the CO2 is released as a gas.

Adding additional sodium hydroxide should not cause a precipitation, since NaOH is composed of parts that are already in the system to begin with. Unless you oversaturate the solution, you should not precipitate anything.
