A weak base always forms a strong conjugate acid. In the case of H3PO4, it forms H2PO4- (dihydrogen phosphate anion) as its conjugate base after removing an acidic proton. Moreover, H3PO4 is a weak acid so according to the conjugate acid-base pair, its corresponding pair, H2PO4−...
On the flip side, a 0.0005 M HCl solution is dilute, yet still strong. Conjugate acid is an acid that formed when the parent base compound gains one proton and the conjugate base is a base that formed when the parent acid compound loses one proton. Is NO2 a weak conjugate base? Expert...

What is the conjugate base of HPO42-? What is the conjugate base of HClO4? Which is the conjugate acid of HPO42-? a. H3O+ b. H2PO4- c. H3PO4 d. PO43- What is the formula for the conjugate base of HBr? What is the conjugate base of NH3?
because it is a weak acid. Equalibrium. As ethanoic acid added into water it immediately dissociates/ionizes to produce H3O+ ions and that's why the solution changes from pH of 7 to < 7. Due to the nature of Weak acid therefore it is a strong conjugate base (CH3COO-) ...
The solution is classified as a buffer if the molarity ratio of the weak acid-base conjugate pair is adjusted close to 1:1. Based on Le Chatelier's principle, the equilibrium must significantly shift left, such that the percent dissociation of the acid b...
Your graphs, which will be used as a template for your lab data, should look like:28 When you titrate a weak acid with a strong base, such as NaOH, the reaction will go essentially to completion, giving an acidic solution until the equivalence point OH– + HC2H3O2 C2H3O2–+ H2O(1) ...
