The pH Scale - The strength of acids and bases can be expressed in terms of the concentration of the hydronium ions or hydroxyl ions in a solution. The concentration of hydronium ions in a solution can be expressed as moles of hydronium ions per litre of solution. This is expressed by a t..

During increased body activity the CO 2 content of blood raises. It combines with water to form carbonic acid in the blood. This lowers the pH, which increases the heart be..

pH is the negative logarithm of H 3 O + ion concentration in moles/litre pH of water = 7 at 298 K pH of acids = less than 7 pH of bases = greater tha..

It is quite clear that the strength of acids and bases can be expressed in terms of the concentration of hydrogen ions, i.e., hydronium ions (H 3 O + ) or hydroxyl ions (OH - ) in a solution. The concentration of hydronium ions in a solution can be expressed as moles of hydronium ions per litre o..

The proteins act as buffers in regulating the acid and base concentration in bloo..

Arrehenius' Concept of Acids and Bases An acid is a substance which can furnish hydrogen ions in its solution. Examples: ..

We have seen that concept of ionic product of water enables us to classify solutions as acidic, basic or neutral by specifying H 3 O + ion concentration. The pH scale was devised by P.L Sorensen (1909) is defined as negative logarithm of hydronium ion concentration in moles per litre. ..
