Question

Define PH value. What is the PH value of water and blood.​

Answer 1

Answer:

In chemistry, pH {denoting 'potential of hydrogen' or 'power of hydrogen} is a scale used to specify the acidity or basicity of an aqueous solution. Lower pH values correspond to solutions which are more acidic in nature, while higher values correspond to solutions which are more basic or alkaline.

Our blood and other body fluids that surround the cells are slightly alkaline (pH from 7.2 to 7.45).

Hope this helps uu!!

➡pH is a scale used to specify the acidity or basicity of an aqueous solution. Lower pH values correspond to solutions which are more acidic in nature, while higher values correspond to solutions which are more basic or alkaline.

➡Even in pure water ions tend to form due to random processes (producing some H+ and OH- ions). The amount of H+ that is made in pure water is about equal to a pH of 7.
