The salt formed when hydrochloric acid (HCl) reacts with sodium carbonate (Na₂CO₃) is sodium chloride (NaCl).

Here's the balanced chemical equation for the reaction:

2HCl (aq) + Na₂CO₃ (aq) → 2NaCl (aq) + H₂O (l) + CO₂ (g)

This reaction produces:

* Sodium chloride (NaCl), which is common table salt.

* Water (H₂O).

* Carbon dioxide (CO₂) gas, which is released as bubbles.
