WebA general equation for a reaction is shown. A (aq) + B (aq) + C (aq) → D (aq) + E (aq) In aqueous solution, A, B, C and D are all colourless but E is dark blue. A reagent (X) is available that reacts rapidly with E. This means that, if a small amount of X is included in the initial reaction mixture, it will react with any E produced until all ... Web1.
