Explain the working of an acidic buffer solution.

An acidic buffer contains

Define pH. What is buffer solution? Derive Henderson-Hasselbalch equation for calculating the pH of an acid buffer solution.

Explain the working of a photo diode.

Higher the amount of acid or base used to produce a definite change of pH in a buffer solutions, higher will be its buffer capacity . Buffer capacity of solution is maximum under the following conditions: [Salt ]= [Acid ](in acid buffer ) ,[Salt ] =[Base] (in base buffer) pH of a buffer solution lies in the range given below : pH= pK_a +1 In other words any buffer solutions can be used as buffer up 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 , Buffer capacity is maximum when:
