WebIn the reaction of a weak acid and a weak base there is no spectator ion. Since there are no spectator ions, the total ionic and the net ionic are exactly the same. Example HF and NH 3. General Equation. HF(aq) + NH3(aq) → NH4F(aq) Total Ionic Equation. HF(aq) + NH3(aq) → NH + 4 (aq) + F − (aq) Net Ionic Equation. WebA witches brew is an apt description of the mixture of carbonyl chlorides of ruthenium(II), which arise from the carbonylation of alcoholic solutions of commercially available hydrated ruthenium chloride “RuCl 3 ⋅H 2 O”.
