The distilling column was packed with metal sponge and the height was measured in centimeters and recorded. The distillation apparatus was assembled and a heat mantle was set. Several vials were used as fraction receivers. The vials were labeled‚ 1-4‚ and weighed prior to adding the liquid mixture and after the liquid was added. The temperature was recorded before adding heat in order to begin distillation (20º C). The temperature was recorded prior to each distillation fraction and after each 2ml

Results and Discussion: A reaction involving two bond formation was employed for the preparation of 3‚5-disubstituted 1‚2‚4-triazole as nucleobase analog. The hydrazides 2a‚b were allowed to react with the heteroaryl substituted acetonitrile derivatives 1a-c using catalytic amount of K2CO3 and n-butanol as a solvent to afford the disubstituted 1‚2‚4-triazoles 3-7 bearing benzothiazole‚ benzotriazole‚ quinoloxymethyl and benziimidazole ring systems in moderate yields.

increased potassium concentration in the CPR solution and the transport of the solution into the tubule (figure 1). The least tubule transport occurred at 0mM potassium (score of 0) and the most tubule transport occurred at 10mM potassium (score of 4) (figure 1). There was a strong positive correlation (R2=0.9871) between increased sodium concentration in the CPR solution and the transport of the solution into the tubule (figure 2). The least tubule transport occurred at 0mM sodium (score of 0.083

GRAVIMETRIC ANALYSIS OF A CHLORIDE SALT (2013) Report By: ____________ Lab Partner: ___________ Group: CHEM 1001 Tuesday AM‚ Group H Purpose: This lab was conducted in order to determine the content of chloride in an unknown salt‚ using gravimetric analysis. Theory: The salt chloride content is easy to find because it is slightly soluble‚ making it possible to turn it into a precipitate. A precipitate reaction can be done using silver
