[Solved]: 19. If a substance has a lot of Hydrogen Ion (H+), BCl3 This means that when calculating the values for Kb of CO32-, the Kb of the first hydrolysis reaction will be \(K_{b1} = \dfrac{K_w}{K_{a2}}\) since it will go in the reverse order. For this reason it cannot be handled in glass test tubes or apparatus during laboratory work. f). Well, there are, No, cotton candy does not have dairy. I found for NH4F to be acidic by finding Ka (NH3) being greater than Kb (HF).
