pH Value Of Acidic And Basic Solutions

The pH values of three acid solutions A, B and C are 1 , 0 and 2 respectively. The order of their acid strength is

The nature of a solution whether neutral , acidic or basic depends upon its pH value. The pH of a solution changes when an acid or base added to it . Howerver the pH of the solution is maintained by the addition of a suitable buffer whether acidic or basic. (i) Define a buffer solution (ii) Give one example each of acidic and basic buffers. (iii) What is the value associated with the use of buffer solution in human beings ?

The nature of a solution whether neutral , acidic or basic depends upon its pH value. The pH of a solution changes when an acid or base added to it . Howerver the pH of the solution is maintained by the addition of a suitable buffer whether acidic or basic. (a) Define a buffer solution (b) Give one example each of acidic and basic buffers. (c) Define pH of a solution .

The range of pH for acidic and basic buffer is where K_(a) and K_(b) are the acid base dissociation constants, respectively.
