Although antacids containing calcium carbonate can increase calcium intake, what effect would excessive consumption of the carbonate base have on blood pH?

The blood pH will increase.

Explanation:

Antacids are the chemicals that works against the acids that produced in our stomach. Antacids are generally used to treat the excessive acidity of the stomach.

The intake of excessive carbonate base causes the release of gastric acid secretion in the stomach. Hence, the blood pH increases due to the presence of H + ions in the blood.

Thus, the blood pH will increase.
