To make bromine water, you need to follow the following steps: 1. Start by putting chlorine in the water. The best way to do this is to dip a funnel into the container, and then drip the chlorine through the funnel into the water. The funnel will spread it evenly across the entire container. If you are using an already made bromine solution ...

The liquid-phase bromination of toluene in a zeolite—bromine—oxirane system has been studied. This system increases selectivity toward the para-bromotoluene isomer due to two factors: first, the oxirane deactivates the sites located on the external surface of the zeolite and, second, a bromine—oxirane complex is formed that is less …

At cathode reduction of water occurs: $$ce{2H2O(l) + 2e- -> H2(g) + 2OH-(aq)}$$ And hydrogen gas is produced. At the anode, where oxidation occurs, the standard oxidation potential of water is –1.23 volts, while that for bromide ions is -1.07 volts. The production of bromine itself has a negative electrode potential.

The water feeds through the chlorinator prior to the return jet and adds chlorine directly into the water. You may wonder why you would use an automatic chlorinator since the chlorine will also be sitting in it creating extremely acidic water just as that of the skimmer when the pump isn't running. The difference is that the chlorinator is ...
