Concentration of the suspended solid can be calculated as below: Concentration of suspended solid = ( A B) 1000 Volume of sample (mL) A = weight of suspended solid + filter paper (mg) B = weight of filter paper (mg) 1 3.0 LITERATURE REVIEW When there is no adequate water sources to meet needs of a community‚ it is necessary

This separates a solid from a liquid through the use of a porous material as a filter. Paper is a good filter. Filters allow the liquid to‚ pass through but not the solid. 5. Evaporation. This is the process of heating a mixture in order to drive off a volatile liquid and make the remaining component dry Materials: beakers Bunsen burner and tubing chemical scoop electronic balance evaporating dish filter paper funnel gloves (disposable) goggles graduated cylinder pipets ring

However instead of a coffee filter‚ a paper towel needs to be cut into a circle and folded into a funnel shape. The filter needs to be placed into the funnel to strain the liquids from the solids. The filter and funnel should be placed into a graduated cylinder to collect any extra juice that is released from the

The minimum duration of a mark or space condition is called the element length. Typical values for element length are between 5 and 22 milliseconds‚ but element lengths of less than 1 microsecond and greater than 1 second have been used.

After the procedure is done‚ there should be a 90% recovery rate. At first the technique of filtration to filter the sand from the salt water is used. Filtration is a procedure that separates a heterogenous mixture‚ with the use of filtration paper. Then the mass of the sand will be found using a balance. A balance is an instrument that finds the mass of an
