In decinormal solution, CH_(3)COOH acid is ionised to the extent of 1.3% . If log 1.3 = 0.11, what is the pH of the solution?

To prepare a buffer solution of pH=4.04, amount of Barium acetate to be added to 100 mL of 0.1 M acetic acid solution [pK_b(CH_(3)COO^(-))=9.26] is:

a. Write an equilibriu equation for a solution containing CH_(3)COOH and CH_(3)COONa . What effect does CH_(3)COONa have on a solution of CH_(3)COOH ? b. What reagents should be added to a solution to increase i. [CH_(3)COO^(Theta)] ii. [overset(o+)NH_(4)]

Aqueous solution of HNO_(3),CH_(3),CH_(3)COOH , and CH_(3)COOK of identical concentrations are given. The pair (s) of the solution which may form a buffer upon mixing is (are):

500 ml of 2 M CH_(3)COOH solution is mixid with 600 ml 12 % w//v CH_(3)COOH solution then calculate the final molarity of solution.

4 gm NaOH is dissolved in 1 litre solution containing 1 mole CH_(3)COOH and 1 mole CH_(3)COONa . Calculate pH of resulant solution. ( K_(a) of CH_(3)COOH=1.8xx10^(-5) , log11=1.04 )

A solutions is 10 M in CH_(3)COONa and 1 M in CH_(3)COOH . If pK_(a) of CH_(3)COOH is 4.8 , what is the pH of the solution?
