Reaction Kinetics

Dependence of the reaction velocity on the type of substanceII

Dependence of the reaction velocity on the temperature I(acetic acid - magnesium)

Saponification rate of tertbutyl chloride

Principle

Tertiary butylhalogenides are saponified in aqueous and aqueous basic solutions according to an S_N1 mechanism to tertiary butanol. The kinetics of the reaction can be followed via the temporal consumption of hydroxide ions and evaluated accordingly.

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 e ...

Halogen exchange rate

Principle

Alkyl halides experience rapid halogen exchange reactions in appropriate solvents. These substitution reactions occur according to an SN2 mechanism.  Their velocity can be advantageously monitored via conductivity measurements if the ion mobilities in question ...

Conductometric measurement of the saponification of esters (with the Cobra3 Basic-Unit)

Principle

Carboxylic acid esters are saponified in an alkaline medium according to the second order reaction rate (law). In the process, hydroxide ions with a high ion mobility are consumed in reaction with an ester. The temporal course of reaction can thus be advantageously ...
