Which of the following statemnets is INCORRECT about sodium carbonate?
Sodium carbonate is used to neutralise excess acid in the stomach.
The correct answer is option 1 i.e. Sodium carbonate is used to neutralise excess acid in the stomach.
Sodium carbonate is a versatile compound with many uses. It is incorrect to say that sodium carbonate neutralises excess acid in the stomach, because sodium bicarbonate, not sodium carbonate, is used as an antacid. Sodium carbonate is indeed used as a cleaning agent for domestic purposes due to its alkaline nature. It is also used in the manufacture of other sodium compounds like borax. Additionally, sodium carbonate plays a significant role in the glass, soap, and paper industries. Therefore, the incorrect statement is the one claiming that sodium carbonate neutralises excess stomach acid.
