Carbamide peroxide (Gly-Oxide) is a stable complex of ureaand hydrogen peroxide. It has the molecular formulaH2NCONH2H2O2. The commercial preparation is a solutionof 12.6% carbamide peroxide in anhydrous glycerin.When mixed with water, hydrogen peroxide is liberated.Carbamide peroxide is used as bo...
The need for heating and very large amounts of coagulant limits the efficiency of this method. Accordingly, this work developed a chemical oxo-preceipitation (COP) method, which uses hydrogen peroxide (H2O2) as the oxidant and barium hydroxide (Ba(OH)2) as the precipitant to improve ...
The chemical formula for calcium hydroxide is: a. {eq}CaO {/eq}. b. {eq}CaOH. {/eq} c. {eq}Ca(OH)_{2} {/eq}. d. {eq}CaO_{2} {/eq}. Molecular Formula: The molecular formula of a molecule is represented in terms of the atomic symbols of constit...
(RT) in dark. ABTS+was diluted with water to obtain equilibration of absorbance 0.70 (± 0.02) at 734 nm and suitable blank was used without adding test samples. 50 mg/mL stock solutions of plant extracts were prepared and different concentrations used for assay. The following formula was...
Konovalov derived the formula that described the kinetics of autocatalytic reactions in the form of the equation (1.4)dx/dt=(k1+k2x)(A−x) where k1 and k2 are the rate constants of the spontaneous and catalytic reactions, A is the concentration of the starting substance, and x is ...

In rove bleaching chlorine compounds are being increasingly replaced by hydrogen peroxide and in fabric bleaching sodium chlorite has almost invariably been replaced by sodium hypochlorite. The Natural Fibres Institute (Poznan, Poland) has shown that flax can be used to help remove heavy metal from ...
