briefly outline the evidence that methyl red and b- cyclodextrin formed a host- guest complex

What is the requirement for a molecule to be active in the Infra Red region?

Lysozyme purified by ion-exchange chromatography was collected from 380 mL egg white. i) The initial rate of the reaction catalyzed by 0.15 mL of 50-fold diluted egg white was 0.320 OD unit min-1. ii) The initial rate of the reaction catalyzed by 0.15 mL of 20-fold diluted pH 10.5 filtrate was 0.900 OD unit min-. If there were 60 mLs of pH 10.5 filtrate collected, what percentage of original activity for egg white was recovered? Show all calculations.

At a pH of 4, the Cu-neocuproine complex formed in the liquid-liquid extraction experiment has a partition coefficient of about 6.0 when equilibrated between the acid aqueous solution and chloroform. Calculate the concentration of Cu in the chloroform phase if 31.0 mL of a 0.27 M aqueous Cu solution buffered to pH 4 is equilibrated with 23.0 mL of chloroform.
