Write the reaction equation salt + hydrochloric acid.

The reaction equation for the salt + hydrochloric acid reaction is as follows:

Salt chosen – sodium carbonate Na₂CO₃

Let’s write the reaction equation:

Na₂CO₃ + 2HCL = 2NaCL + H2O + CO2

We placed the coefficients. The exchange reaction occurs as a volatile compound, carbon dioxide, is released. The reaction between salt and acid occurs when a precipitate or gas may form. In our case, carbon dioxide was released.
