When acids and bases react with each other, the product is a salt made out of the acid's anion and the base's cation, and the other product is water. What would water be like with 2 parts oxygen? Neither of these ions will affect the pH, so NaBr is neutral. If the cation is a weak Lewis acid, it will not affect the \(pH\) of the solution. is the conjugate base of a weak acid it is a weak base. A strong acid has a weak conjugate base. So NaBrO must be more basic than NaBr. Is Ag+ acidic? Identify Conjugate Acid or Base a) What is the conjugate acid of CO 3 2-b) What is the conjugate base of H PO 4-? NH4Cl is a weak acid, whereas HCl is a strong acid. If an ion originated from a strong acid or base, it has no effect on salt pH. This makes NH4 an acidic ion, meaning NH4Cl is an acidic salt. red.
