pH of buffer solutions

The buffer solution of 100 ml having a pH value 4 when added to 1 ml dilute HCl , then the pH of buffer solution

When small amount of an acid or alkali is mixed with a buffer solution, then pH of buffer solution

In a buffer solution containing equal concentration of B^(-) and HB , the K_(b) for B^(-) is 10^(-10) . The pH of buffer solution is

The pH of buffer solution containing 4 xx 10^(-3) and 0.4 mole of acetic acid (pK_(a) = 4.76) and sodium acetate respectively will be

A buffer solution contains 0.04 M HA and 0.01 M CaA_(2) . If K_(b) of A^(-) is 10^(-12) then pH of buffer solution is Given : log 2 = 0.3

Higher the amount of acid or base used to product a deinite change of pH in a buffer solution, higher will be its buffe capacity. Buffer capcity of solution is maximum under the following conditions [Salt] = [Acid](in acid buffer) [Salt] = [Base] (in base capacity] pH of buffer solution lies inthe range given below pH = pH_(a) +-1 In other words,any buffer solution can be used as buffer up to two pH units only, depending upon the value of pK_(a) or pK_(b) . A buffer is said to be efficient when pH = pK_(a) or pOH = pK_(b) Which among the following solution will the most efficient buffer
