Question

what is ph give the biological importance of ph​

Answer 1

definition :-.

In chemistry, pH (/piːˈeɪtʃ/, denoting 'potential of hydrogen' or 'power of hydrogen'[1]) is a scale used to specify the acidity or basicity of an aqueous solution. Acidic solutions (solutions with higher concentrations of H+ ions) are measured to have lower pH values than basic or alkaline solutions.

$importance$

pH is important because substances such as our stomach acids tend to be at a certain pH in order to work properly. pH is also important because it must be at certain levels in order for living organisms to survive. Create a large pH scale (two or three meters long).

Answer 2

Answer:

A scale for measuring hydrogen [H+(aq)] concentration in a given solution, is called pH scale,we can masure pH from zero(very acidic) to 14(very alkaline) .so, pH donates numbers whch indicates acidic o basic nature of a solution. Higher the H+(aq)/H3O+(aq) number,lowe is the pH value. The pH of neutral solution is 7.value less than 7 on the pH scale represent an acidic scale. value more than 7 indicates alkaline solution which indicates increase on OH-(aq) ions.

Imlortance of pH :-

(i) when pH of saliva goes down mouth below 5.5 it can cause tooth decay.

(ii) Animals and Plants are pH sensitive..

(iii) pH of HCL secreted in stomach is 2.0 which is acidic. pH of intestinal juce is 7.8 which is basic.

(iv) self defence by animal.
