ie, HPO42- is acting as a base rather than an acid. the definition for the conjugated acid: the acid that will be formed when the base dissociates.
-is the conjugate base of HC 2H3O2. The conjugate base of a molecule or ion is the molecule or ion that forms when one H+ ion is removed. The formulas HC2H3O2 and C2H3O2-represent a conjugate acid-base pair. EXAMPLE - Conjugate Acids: Write the formula for the conjugate acid of (a) F-, (b) NH3, (c) HSO4-, and (d) CrO 4 2-. Solution: Acids do have an H+ But a base is ANYTHING that can accept a proton - it doesn't have to have an OH-. Anything with a negative charge or just non-bonding electrons (N, O, P) can act as a base. The salt formed by the dissociation of an acid is the "conjugate base" of the acid. This must mean that the...

A conjugate base contains one less H atom and one more - charge than the acid that formed it. Let us take the example of bicarbonate ions reacting with water to create carbonic acid and hydronium ions. What is the conjugate base of HCl? HCl is a strong acid. When it donates a proton, a Cl – ion is produced, and so Cl – is the conjugate base. Sep 09, 2018 · However, this was not the case, because the concentration of the conjugate base (HCO 3 –) was ten times more than the concentration of the conjugate acid (H 2 CO 3). This means as we divide a smaller concentration value by a larger one, we should expect the concentration of H 3 O + to be less than the K a .
