calculate pKa values from he following Ka's= a) nitromethane, Ka= 5.0 x 10 ^-11 b) acrylic acid, ka = 5.6 x 10^-5
OH pka 3.1 pKa 4.5 HO -OH pka 5.8 depicts the structure of citric acid with the corresponding pka values for each of the three acids. a. Explain why the carboxylic acid at the top of the structure is the most acidic. b. Suggest a reason why the remaining two acids would have different pka values.
Calculate the Ka value for the following acids. (Enter your answer to three significant figures.) a) Nitric acid (pKa = -1.30): b) Acrylic acid (pKa = 4.25)
The Pka of acrylic acid is 4.25. What is the concentration of H3O+ in .190M, C3H3O2- in .190M, HC3H3O2 in .19M, OH- in .19M, and the % dissociation in .05M acrylic acid The pH in .19M of acrylic acid is 2.49 Could someone please show me the steps to this? Thanks

Which acid is stronger, acetic acid (pKa = 4.75) or citric(II) acid (pKa = 4.74)? Why?
Ka = 10^(-pka) if ka is 1.8E-5 then, solve for Pka for acetic acid.
