1. t-butylchloride, propanol and acetone are flammable, toxic in high concentrations, and irritants the eyes and skin. They should not be: used around open flames, ingested, come into contact with eyes/skin.
4. The volumetric flask must be completely dry before adding t-BuCl because any amount of water will distort the results of the experiment and the C-Cl bonds will be broken and replaced by C-OH bonds. 5. The infinity samples are added to water instead of the mixture because the high concentration of water will help the reaction reach completion much faster and determine the HCl concentration.
8. The samples are added to acetone to quench the reaction because the hydrolysis reaction is slower in acetone, which is effective for quenching.
9. [RX]t in this experiment represents the concentration of the reactant at a specific time ‘t’.
10.[HX]inf represents the infinity sample – which in this experiment is the concentration of HCl after a complete reaction.
11. Bromothymol Blue is blue in basic solutions.
