For weak acids, the position of the Ka and pKa values that characterise the equilibrium dissociation can be determined in the ground state through photometric measurements […]
The experiment enables you to determine the absorbance of an aqueous solution of thymol blue in hydrochloric acid and dilute sodium hydroxide and a buffer of […]
Through the system provided you will measure the extinction coefficient of various concentrated solutions of trans-azobenzene in acetonitrile at a constant wavelength.
In the spectral region between 200 and 800 nm, which is recorded by UV-VIS spectrophotometer, you have transitions of electrons from the basic state to the […]
Spectrometry is an important analytical method for qualitative and quantitative determination of certain substances using the index of refraction of the material and lamps with emission […]
Through this apparatus the rotation of the polarisation plane is measured through a sugar solution with a polarimeter and the constant for the reaction rate for […]
