19. The ph range of an ideal antacid is
A. 13-14
B. 5-7
C, 6-8
D. 10-11
Answers
Answer: Option (D) is the correct answer.
Explanation:
An antacid helps in removing or neutralizing the excessive acid formed in the stomach.
It is known that substances whose pH is less than 7 are acidic in nature whereas substances whose pH is more than 7 are basic in nature. On the other hand, substances whose pH equals 7 are neutral in nature.
Since, antacids are basic in nature as they neutralize the acid hence, the pH range of an ideal antacid is 10-11.
Answer:
The pH range of an ideal antacid is D. 10 - 11
Explanation:
An antacid is a alkaline chemical substance used medicinally to neutralize excess acid in the stomach and relieve symptoms of hyperacidity.
Hyperacidity is the process by which excess gastric acid is produced in the stomach.

pH ranges of 1 - 6 is of acidic solutions
pH of 7 is of a neutral solution
pH ranges of 8 - 14 is of alkaline/basic solutions.
----------------------------------------------------------------------------------------------------------------
Antacids are bases, both choice A and D are pH ranges of bases.
However, pH ranges of 13 - 14 cannot be used as antacids because such high pH values are corrosive to the skin. Such high pH values can cause blood alkalosis.
Blood alkalosis is when the pH of the blood is at higher values ( basic).
