Reaction rate and activation energy of the acid hydrolysis of ethyl acetate

Principle

In acid solution, ethyl acetate is hydrolysed to equivalent quantities of ethanol and acetic acid according to a pseudo-first order rate law. The alkalimetric determination of the acetic acid formed enables conclusions to be drawn on the temporal concentration of ...

Determination of the Michaelis constant with Cobra4

Principle

The enzymatic hydrolysis of urea in aqueous solution liberates carbon dixide and ammonia. The ions of these compounds increase the conductivity of the solution. Conductivity measurements can so be made to determine the rate of hydrolysis of urea by the enzyme urease at various ...

Behaviour of salts with regard to solvents of different

Principle

Salts dissolve better in polar solvents than in non-polar solvents. If there are two solvents of different polarities, salts can change from the non-polar phase to the polar one and dissolve there. The behaviour of soluble salts in a water-oil-mixture are studied in this
