The pH of buffer solution prepared by mixing `50 mL` of `0.2 M CH_(3)COCOOH` and `25 mL` of `CH_(3)COONa`? `P^(Ka)` of `CH_(3)COOH = 4.8`

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 ?

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 )

The pH of a solution obtained by mixing 100mL of 0.3M CH_(3)COOH with 100mL of 0.2 M NaOH would be: ( pK_(a) for CH_(3)COOH=4.74 )
