Document Summary

Rheostats are used to adjust the temperature of heating mantles (thermowells) since they have no regulating device. A refractometer is used to take r. i. readings (can be used to determine [solution]) Waste disposal with a lot of water waste container. Aqueous-based solution (e. g. dilute hcl, h 2 so 4 , naoh, nahco 3 ) flushed down sinks. Water-immiscible (most organic) or flammable organic solvents liquid organic these contents have to be burned in special incinerators (no water-based solution) Solid organic/inorganic compounds, paper and corks that came in contact with any. Paper that has not come in contact with any chemicals or solvents (except water) . Acetone acetone waste only container (recycle) chemicals, tlc plates solid waste container. Often used in extraction: excellent solvent properties and immiscible with water. Useful for separating mixture when the components have different b. p. If two volatile liquids b. p. has to be . Refractive index (r. i. ) of the liquid measure of change in refraction.
