What is meant by a weak acid? Acid Dissociation Constant: Ka Answer and Explanation:1 The strength of an Arrhenius acid is solely indicated by the magnitude of its dissociation constant. We consider the dissociation equilibrium of a...
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...
