Classification of fruits 1. Berries – usually succulent fruit and very juicy. The availability of berries is between May and August. But grapes are berries that can be found year round. Some foods classified as berries do not fit the botanical definitions like strawberries and raspberries but are berries. There are fruits that are true berries but are not classified into other categories e.g. bananas and grapes. Berries grow in bunches in bushes and on vines. They are small and juicy. Examples

Objective: To extract caffeine from tea powder using polar - nonpolar solvent extraction technique. Theory: The technique used to separate an organic compound from a mixture of compounds is called Extraction. Extraction process selectively dissolves one or more of the mixture compounds into a suitable solvent. The solution of these dissolved compounds is referred to as the Extract. Here the organic solvent dichloromethane is used to extract caffeine from an aqueous extract of tea leaves

Berry DNA Extraction Lab I. Problem Statement: Successfully extracting the DNA from strawberries. II. Background info: DNA is the genetic information in organisms that codes for proteins‚ and controls the cells function. The DNA is a double helix molecule that is formed by various nucleotides which include Adenine‚ Thymine‚ Guanine‚ and Cytosine with sugar phosphate. Different organisms can have larger or smaller genes. DNA is also what makes up chromosomes during cell replication. Strawberries

EXTRACTION OF METALS SUMMARY Most metals exist in compounds in rocks in the Earth’s crust. Many of these ores contain oxides or sulphides of the metals. The compounds need to be reduced to produce the metals as elements. Metals are very useful to us because of their special properties. Reduction means removal of oxygen or gain of electrons. Carbon is a good chemical reducing agent because it readily combines with oxygen‚ but it is only useful for the metals below it in the Reactivity

SOLVENT EXTRACTION Solvent extraction‚ also known as liquid extraction and partitioning‚ is a method to separate compounds based on their relative solubility in two different immiscible liquid‚ usually water and organic solvent. It is an extraction from one liquid phase to another liquid phrase. Liquid extraction is a basic technique in chemical laboratories‚ where it is performed using a separator funnel. This type of process is commonly performed after a chemical reaction as part of the work-up

Extraction Report For experience 4c we were supposed to determine which one is the organic layer in three different tubes that has two layers. To determine which is aqueous (water) or organic‚ I used the technique of adding droplets of water to each tube. If the layer is water‚ then the drops of added water will dissolve in the aqueous layer and increase it’s volume. If the added water form droplets or a new layer‚ then it is the organic layer. Tube 1 (water and n-butyl chloride)‚ after adding
