Question

Our body works within the pH range of:
A. $6 - 6.5$
B. $7 - 7.8$
C. $8 - 9$
D. $6.5 - 7$

Answer 1

The pH range of the human body is a vital component for carrying out several biological functions. The human body works according to the pH range. Lower or higher pH is harmful to the human body.

Complete step by step answer: pH is referred to as the potential of hydrogen ion concentration which indicated the acidity or basicity of an aqueous solution. The pH scale ranges from 0-14 . The pH value less than $7$ is called acidic and higher than $7$ is called basic.
Human body maintains a specific pH to work properly. Our body works well within the pH range of $7 - 7.8$
The pH value less than $7$ generates various disorders inside the body. Disorders like acidity problems, dizziness or even severe disorders like coma stages are normally encountered. The pH of blood is found as $7.4$ .
If the pH of the stomach gets too low then it results in indigestion. The milk we take changes with acidic pH and causes pain in the stomach and we vomit sour taste. The mouth contains excess acid which is neutralized by the toothpaste.
Acidity problems reveal that acid levels in the stomach are in excess. Hence antacid is used which contains basic salt. The antacid reacts with excess acid from the stomach and neutralizes. Commonly used antacids contain calcium carbonate, magnesium hydroxide, aluminum hydroxide and/or sodium bicarbonate.
So, the correct answer is “Option B”.

Note:
The pH range must be maintained properly for avoiding malfunctioning. The cell stays alive at alkaline pH in our body.
