The color of the pH indicator Bromothymol blue (BTB) changes from yellow to blue with increasing pH. The effect of some electrolytes (LiCl, NaCl, KCl, CsCl, KSCN and KClO3) and of D2O on the spectral properties of dilute solutions of BTB is explored. The results are interpreted in terms of dimerization of the dye mols. and of the different hydration that D2O induces. The effects of dissolved gases on the spectral properties of BTB is studied. Complete removal of dissolved gas is achieved. Surprising effects on the UV-vis spectra emerged. After degassing solutions, gases were re-admitted via bubbling. The gases He, Ar, N2, CO2 and CH4.were studied. The effects can be explained by presence or absence of nano- and microbubbles of gas in the solution These allow formation of dimers and multiple association via adsorption and so affect the spectral properties of the dye mols. This study involved multiple reactions and reactants, such as Lithium chloride (cas: 7447-41-8Product Details of 7447-41-8).
Lithium chloride (cas: 7447-41-8) belongs to organic chlorides. Organochlorines are organic compounds having multiple chlorine atoms. They were the first synthetic pesticides that were used in agriculture. They are resistant to most microbial and chemical degradations. Aryl chlorides may be prepared by the Friedel-Crafts halogenation, using chlorine and a Lewis acid catalyst.Product Details of 7447-41-8
