There is two tube A and B, A contains Br- and BrO3- and B cotains sulphuric acid.
Why does the reaction not start until the content of the two tubes are mixed?
Is it due to the electostatic repulsion between negative chareged ion in A causing no reaction in tube A?
If it is true, why does the reaction start if two contents of the tubes are mixed? How will the acid affect the reactant in tube A to make the reaction occur?
