Calculating concentrations

Calculating concentrations. The concentration of a solution can be measured in grams per dm 3 (g/dm 3 ) or moles per dm 3 (mol/dm 3 ). The following equation gives concentration in g/dm 3 :. mass dissolved (g). concentration =. volume of solution (dm 3 ).

Kinetic Study of Hydrolysis of Di-3-Chloro-2- Methylaniline Phosphate in Acid Medium

Kinetic study of the hydrolysis of di-3-chloro-2-methyl aniline phosphate has been carried out in the acid region, 0.5 to 7.0 mol dm-3 HCl at 800 C in 40% (v/v) dioxane-water medium. The rate of hydrolysis increases with increase in acid molarity up to 4.0 mol dm-3 HCl and after that it decreases. The lowering of rate after 4.0 mol dm-3 HCl has been attributed to the effect of water activity. Ionic strength data is used to identify reactive species and find out theoretical rates. Bimolecular behaviour of the hydrolytic reaction has been decided by Arrhenius parameters, Hammett acidity function, Zucker Hammett equation, Bunnett and Bunnett-Olsen parameters. Solvent effect on hydrolytic reaction has been found to indicate the formation of a transition state in which charge dispersion occurs.
