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

Hint: Human body works within a narrow range of pH. More value of pH or less value of pH both the conditions are harmful. In order to survive, the human body needs to keep balance on pH value.

Complete step by step solution:
* pH or potential of hydrogen is generally used to describe the acidity or basicity of an aqueous solution.
* pH scale has values from 0 to 14. pH of 7 is called neutral, less than 7 is called acidic and greater than 7 is called basic.
* Our body needs to maintain a healthy balance of acidity and alkalinity to work properly.
* Our body works within the pH range of 7-7.8. Therefore, we can say that pH of our body is slightly alkaline.
So, we can say that option B is correct.

Additional Information:
* If the pH of our body drops to 6.9 then we will be in coma. At 6.8 there are changes of our death.
* The normal pH range for our arterial blood is 7.35-7.45.
* When our body fluid contains too much acid, the condition is known as acidosis.

Note: pH balance is very important for proper functioning of the human body. Cells must maintain alkalinity in order to function and stay live. Human skin is generally alkaline because soap is alkaline.
