Answer 2

Answer:

Stomach acid is lessened by sodium bicarbonate. Heartburn, indigestion, and upset stomach are all conditions that it is used to treat as an antacid. One particularly effective antacid is sodium bicarbonate. Only brief relief should be obtained from it.

Explanation:

• Baking soda, commonly known as sodium bicarbonate, works by neutralizing excess stomach acid to treat heartburn, sour stomach, and acid indigestion. It is said that when taken for this purpose, it belongs to the class of medications known as antacids. It can be applied to treat the signs and symptoms of duodenal or stomach ulcers.
• Antacids function by neutralizing stomach acid and are weak bases. With a pH little above 7, sodium bicarbonate is a weak base.
• When sodium bicarbonate is dissolved in liquids like blood or urine, it separates into sodium and bicarbonate. This breakdown reduces the blood's acidity and serves as a buffer. This ability to neutralize acid helps alleviate problems like indigestion brought on by excessive stomach acid that is linked to high acidity in body fluids.
• Hence sodium bicarbonate is a mild base that neutralizes the acidity of gastric juice.
