Generic acid base formula

WebYou can use generic formula HA for the monoprotic weak acid. Strong base used for titration is NaOH. Estimate the pH and volume of NaOH added at equivalence point. Explain why pH at equivalence point in the titration of the weak acid by a strong base is different from that of the strong acid. Expert Answer Previous question Next question WebIf it were the same reaction (with an acid and its conjugate base, it would be this way: Ka = (A-)* (H3O+)/ (HA) And Kb = (HA)* (OH-)/ (A-) Clearly, ka =/ 1/Kb : one has H3O+ and the other has OH- (the others are in the equation, but in …

WebIt's acetic acid and instead they might know it from its chemical formula C2H4O2. As someone becomes more familiar with organic functional groups it should be obvious that it's a carboxylic acid and should therefore act as the acid in the reaction. WebLet's start by calculating the H 3 O +, HClO 2, and ClO 2- concentrations at equilibrium in an 0.10 M solution of chlorous acid ( Ka = 1.1 x 10 -2 ). HClO 2 ( aq) + H 2 O ( l ) H 3 O + ( aq) + ClO 2- ( aq ) The first step, as always, involves building a representation of the problem. We then substitute this information into the Ka expression.
