Titrando High-end potentiometric titrator that meets any requirements: Do this by repeating 9. Background Bromine number, or bromine index, is a parameter used to estimate the amount of unsaturated aliphatic groups olefins in a hydrocarbon. The endpoint of the titration has no bias because the value of bromine number can be is achieved when the potential reaches the pre-set value see defined only in terms of a test method.
If you feel that your comments have not received a fair hearing you should make your views known to the ASTM Committee on Standards, at the address shown below. Bromine number is expressed as grams of bromine reacted with g of a sample and it can be measured by titration of a sample with a bromide-bromate solution as titrant. These form deposits in a fuel system or in a carburetor and can clog up both filters and the narrow tubing that supplies fuel to the internal combustion engine.
