The Ka for acetic acid (CH3COOH) is 1.8x10^-5. What is the Kb (to two decimal places) for its conjugate base at 25 C?
The ans is: 5.56x10^-10, but I can't figure it out.
The Ka for acetic acid (CH3COOH) is 1.8x10^-5. What is the Kb (to two decimal places)...
The Ka value for acetic acid, CH3COOH(aq), is 1.8x10^-5. Calculate the ph of a 2.80 M acetic acid solution. PH= Calculate the ph of the resulting solution when 3.00 mL of the 2.80 M acetic acid is diluted to make a 250.0 mL solution. PH= Answers are not 4.6 or 3.8
