A phase transfer catalyst or PTC in chemistry is a catalyst which facilitates the migration of a reactant in a heterogeneous system from one phase into another phase where reaction can take place. Ionic reactants are often soluble in an aqueous phase but insoluble in an organic phase unless the phase transfer catalyst is present. Phase transfer catalysis (also PTC) refers to the acceleration of the reaction by the phase transfer catalyst. Phase transfer catalysts for anion reactants are often

September 19‚ 2014 Period 4 Lab #1: Density Determinations for Solutions Theory: The density of a sample of matter is very useful when trying to find the identity of an unknown substance. The units of density are quoted in (g/mL) for liquid samples of matter. For that reason if the volume is known of a liquid‚ determining its density is easily determined by weighing it accurately. Density can also be used as a tool for finding the concentration of solutions in some cases. The density is different
