- Calculate the pH at 25°C of a 0.68 M solution of potassium butanoate (KC3H7CO2). Note that butanoic acid (HC3H7CO2) is a weak acid with a pKa of 4.82.Dicarboxylic acids have two dissociation constants, one for the initial dissociation into a monoanion and one for the second dissociation into a dianion. For oxalic acid, HO2C—CO2H, the first ionization constant is pKal = 1.2 and the second ionization constant is pKa2 = 4.2. Why is the second carboxyl group far less acidic than the first?In my slide, there is a table summarizing the pKa values for different acids. (1) when ranking the acidity level (how strong the acids are), a low pKa means high acidity. Why is that? (2) Calculate the phosphoric acid solution pH when the ratio of [H2PO4-]/[H3PO4] is 0.8.
