[50ml" of "0.1MNH_(4)OH,25ml" of "2MNH_(4)Cl" were used to make a buffer.What is the "pH" if "],[pK," is "4.8.]

50 ml of 0.1 M NH_(4)OH, 25 ml of 2M NH_(4)Cl were used to make a buffer. What is the pH if pK_(a) is 4.8?

When 20 ml of 0.1 MNH_(4)OH are added to 20 ml of MNH_(4)Cl solution, the pH of the buffer formed is 8.2. What is the pK_(b) of NH_(4)OH ?

50 mL of 0.1 M NaOH is added to 75 mL of 0.1 M NH_4Cl to make a basic buffer. If pK_a" of "NH_4^+ is 9.26, calculate pH.

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 prepared by mixing 50 ml of 0.2 M CH_(3)COOH and 25 ml of CH_(3)COONa is 4.8. If the pK_(a) is 4.8, what is the strength of CH_(3)COONa ?
