Just Chemistry- The techniques

Ms. Allison Classroom

Lesson 3

 Evaporation
Shows a beaker with a mixture of solid and liquid in it. Another beaker has a funnel with some filter paper in.

 Crystallization



















Filtration
Filtration is any of various mechanical, physical or biological operations that separate solids from fluids (liquids or gases) by adding a medium through which only the fluid can pass. The fluid that passes through is called the filtrate.

Simple Distillation




















Fractional Distillation


















Paper Chromatography 

 This is good for separating dissolved substances that have different colours, such as inks and plant dyes. It works because some o1f the coloured substances dissolve in the liquid better than others, so they travel further up the paper.

Just Chemistry- Introduction

Image
Ms.Allison's Classroom Lesson 1 In our everyday lives we often carry out our daily activities without even realizing that we are using scientific techniques.If you've ever forgotten a pot of salt water on the stove - and observed that the water dries out to leave the a white substance (salt) or used a magnet to pick up pins just for the fun of it, you really are observing Separating Techniques. A mixture is a physical combination of different substances which are mixed together but are not chemically combined, believe it or not no matter what the mixture contains it can be separated with right techniques.There are more than ten (10) methods by which we can separate mixtures, Fig.1 below shows concept map of a few.       Fig.1 A Concept Map Showing Some Common Separating Technique  What are the types of separation techniques?

Just Chemistry - Lab Safety

Ms. Allison's Classroom Less on 2 Before we explore separating techniques we have to be reminded that it is important to take care when doing e xperiments: handling chemicals and so on. Refusal to take care in being careful may not only cau se danger to ones self  but cause danger to your class mates. Assuming you were at the class where we reviewed Safety Rules Try filling this sheet out on your own. If you have difficulty feel free to revise your notes.
