💡 Explanation:

An antacid is a substance which neutralises stomach acidity and is used to relieve heartburn, indigestion or an upset stomach.
Antacids contain alkaline ions that chemically neutralise stomach gastric acid, reducing damage and relieving pain.
Examples of antacids are-
Sodium hydrogencarbonate,Magnesium hydroxide,Aluminium carbonate,Aluminium hydroxide.

Sodium carbonate known as washing soda is quite alkaline in nature and has a horrid soapy taste. It is not very palatable and could burn the throat. Bicarbonate is much gentler and not as strongly alkaline, and therefor more palatable. Hence, it will not act as Antacid.
