So, to generalize this; if you need to choose a base to deprotonate a compound that has, for example, a p K a = 10, you can pick anything from the p K a table that has a p K a > 10 and use its conjugate base. In this case both NH 4 + and H 2 PO 4-could enter into acid-base reactions with water and contribute to the pH of the solution, so K A (or pK A) values need to be considered. These cookies track visitors across websites and collect information to provide customized ads. Arrhenius's theory for acid: According to Arrhenius's theory for acid, the substance which produces an H + ion or proton on dissolving in an aqueous solution is categorized as an acid. What are the products formed when potassium carbonate reacts with nitric acid? Neglecting the $\ce{OH^-}$ produced by the autoprotolysis of water, it is valid to make the usual assumption that $\ce{[OH^-]}={[HCO_3^-]}$,and little of the carbonate goes to bicarbonate,so$\ce{[CO_3^{-2}]}={[CO_3^{-2}]_0}=0.5$ ,so thus Potassium carbonate is relatively non-toxic.
