A bromophenol is an organic compound consisting of hydroxyl groups and bromine atoms bonded to a benzene ring. They may be viewed as hydroxyl derivatives of bromobenzene , or as brominated derivatives of phenol .
Bromophenol is also used as a colour marker to monitor the process of agarose gel electrophoresis and polyacrylamide gel electrophoresis.Since bromophenol blue carries a slight negative charge at moderate pH, it will migrate in the same direction as DNA or protein in a gel; the rate at which it migrates varies according to gel density and buffer composition, but in a typical 1% agarose gel in ...
Pauling's second rule is that the value of the first pK a for acids of the formula XO m (OH) n depends primarily on the number of oxo groups m, and is approximately independent of the number of hydroxy groups n, and also of the central atom X. Approximate values of pK a are 8 for m = 0, 2 for m = 1, −3 for m = 2 and < −10 for m = 3. [28]

For K′ 3 there are three different dissociation constants — there are only three possibilities for which pocket is filled last (I, II or III) — and one state (I–II–III). Even when the microscopic dissociation constant is the same for each individual binding event, the macroscopic outcome (K′ 1, K′ 2 and K′ 3) is not equal. This ...
