The acid dissociation constant of bromous acid, K a = [H +][BrO − 2] / [HBrO 2] , was determined using different methods. The value of the pK a for bromous acid was estimated in research studying the decomposition of bromites. The research measured the rate of bromite decomposition as a function of hydrogen and bromite ion concentrations.
Bromous acids and bromites are very unstable, although the strontium and barium bromites are known. [13] More important are the bromates, which are prepared on a small scale by oxidation of bromide by aqueous hypochlorite, and are strong oxidising agents. Unlike chlorates, which very slowly disproportionate to chloride and perchlorate, the ...
A stirred BZ reaction mixture showing changes in color over time. The discovery of the phenomenon is credited to Boris Belousov.In 1951, while trying to find the non-organic analog to the Krebs cycle, he noted that in a mix of potassium bromate, cerium(IV) sulfate, malonic acid, and citric acid in dilute sulfuric acid, the ratio of concentration of the cerium(IV) and cerium(III) ions ...

The function of the Lewis acid is to bind to and stabilize the anion that is formed upon dissociation of the Brønsted acid, thereby removing a proton acceptor from the solution and strengthening the proton donating ability of the solution. For example, fluoroantimonic acid, nominally (H 2 FSbF
“There are certain types of lactic acid bacteria that grow naturally in the grass in these regions,” says Bertinelli. “This bacteria gets transferred to the cow and ends up in the cheese ...
The Research 2000 North Carolina Poll was conducted for Change Congress from October 31 through November 1, 2009. A total of 600 likely voters who vote regularly in state elections were interviewed statewide by telephone. Those interviewed were selected by the random variation of the last four digits of telephone numbers.
