The act of pouring a mixture onto the membrane that allows a passage of liquid and results in the collection of solid

Uses glass funnel with a stem and filter paper folded using basic technique or fluted type

It involves distribution of a solute in two immiscible solvents

A process in which the components of the mixtures are separated by pouring out liquid so as not to disturb the solids that readily settle at the bottom of the container

A process in which the solid of highly vapor pressure passes directly to the gaseous state without passing through the liquid state

A process of separating liquid mixtures with the components of varying degrees of volatility or significant differences in boiling point

A process of separation in a complex mixtures by their different affinities to an adsorbent at different rates

Volume of liquids is ordinarily measured using: except for

The curved upper surface of a column of liquid which is produced in response to the surface of the container

It occurs when the molecules in sample have a stronger attraction to each other than to the container

It occurs when the molecules of the sample are more attracted to those of the container than to themselves

All equipment must be cleaned and dried after the exercise because traces of impurities may interfere with the many qualitative tests

Analysis are measured dropwise of the sample solution

A balance tube containing a volume of water equal to the volume of solution to be centrifuged is always placed in the centrifuge exactly opposite the solution

A balanced load in the centrifuge will cause severe vibrations and damage to the centrifuge's bearings

When coagulated, the supernatant liquid becomes transparent or clear

If you are using an analytical balance, close all the doors before taking measurements

The volume of the object is equal to the sum of the readings on the three beams

Calibration must be properly done

Small volumes in small test tubes are used using Ordinary droppers

Small volumes in small test tubes are used using capillary pipet

Colloidal Suspensions are too big to be separated by filtration or centrifugation

Precipitate will usually settle, in a good centrifuge, in less than a minute's time

Usually a precipitate is washed thrice, and the third wash liquid is discarded

Avoid disturbing the precipitate as the liquid is withdrawn

The first wash liquid should be added to the separated solution by means of a capillary pipet or micropipette

The most satisfactory method of heating solution in a test tube is in a water bath

A pipet is inserted into the test tube and rotated constantly to break up bubbles of steam

For testing acidity, a red litmus paper is used

For testing basicity, a blue litmus paper is used

Smell the solution by wafting
