A buffer solution is prepared by mixing 0.1 M ammonia and 1.0 M ammonium chloride. At 298 K, the `pK_(b)` of `NH_(4)OH` is 5.0. The pH of buffer is :

A solution is prepared by mixing 100 ml of 0.1 M NH_(4) OH and 200 ml of 0.2 M NH_(4) Cl . pK_(b) of NH_(4) OH is 4.8 . Then the pH of the solution is

The pH of a buffer solution formed by mixing 30ml of 0.1 M NH_(4) OH and 30ml os 1M NH_(4) Cl solution is 8.6. The pK _(b) of NH-(4) OH is

What is the pH of solution obtained by mixing 100 mL of each 0.2 M NH_(4)Cl and 0.2M NH_(4)OH , if pK_(b) of NH_(4)OH is 4.2 ?

What is the pH of solution obtained by mixing 100 mL of each 0.2 M NH_(4)Cl and 0.2M NH_(4)OH , if pK_(b) of NH_(4)OH is 4.2 ?

The pH of a buffer solution prepared by adding 10 mL of 0.1 M CH_(3) COOH and 20 mL 0.1 M sodium acetate will be ( given : pK_(a) of CH_(3)COOH = 4.74 )

The pH of a buffer solution prepared by adding 10 mL of 0.1 M CH_(3) COOH and 20 mL 0.1 M sodium acetate will be ( given : pK_(a) of CH_(3)COOH = 4.74 )

A buffer solution is prepared by mixing 10ml of 1.0 M acetic acid & 20 ml of 0.5 M sodium acetate and then diluted to 100ml with distilled water. If the pK_(a) of CH_(3)COOH is 4.76 . What is the pH of the buffer solution prepared?
