Apples vs. Oranges Although apples and oranges are both fruits‚ they each have many similarities and differences. Some differences are the where they’re grown‚ color‚ tastes‚ appearance and many others. The ways that they are similar are that they have the same shape‚ grown on trees‚ both are fruits and have juice. The exact definition of an apple is the” fleshy usually rounded red‚ yellow‚ or green edible pome fruit of a usually cultivated tree (genus Malus) of the rose family”. The most common

understand the experiments ahead of time; no more reading should be done during lab session. If you do not do this‚ you will be unable to plan and use your time efficiently. There are several lab techniques that you need to read on your own for each lab session for example distillation‚ extraction‚ crystallization etc. They are self-explanatory and if you are unclear about something always consult the lecturer. Students must write/draw a brief outline/flowchart of the procedure of the experiment before coming

Experiment : 1 Tittle : Preparation of bis(acetylacetonato)copper(II) complex Objective : To synthesis the bis(acetylacetonato)copper(II) complex Introduction : A complex ion is usually form with high charge density metal ion as a central and formation of coordinate covalent bond (dative bond) with high electron molecules or ions. These molecules or ions are functioning as ligands (electrophile in organic compounds). They are easily attracted by electrophile (electron deficiency

investigate the vitamin C content of fruit juice * To investigate which type of fruit juice provides the most vitamin C The quantity of vitamin C in food and drink can be determined using a simple colour test. Vitamin C decolourises the blue dye DCPIP (dichlorophenolindolphenol). Vitamin C is an antioxidant and reduces the DCPIP. DCPIP changes from blue to colourless (or slightly pink) as it becomes reduced. We will be testing a range of different fruit juices to see which contains the

extraction of pectin from orange peels has been studied at different sample to solvent ratios‚ different PHs and with different extraction techniques using water. The amount of pectin extracted reduces as the PH increased. This research work is been carried out in order to determine the process condition that will result in high yield of pectin and residual oil extracted from orange peels using the methanol pre-treatment to extract orange peel oil and hydrochloric acid for pectin extraction.

the experiment was performed to conduct quality control analysis on two commercial products to determine the amount of acid or base active in these two products and then compare the results to those of the manufacture. This was done through the preparation of standardized acid solution and standardized base solution‚ and through titration. The purpose of titration was to determine the concentration levels of the commercial products being used. Methods and Materials Week One: the experiment started

Purpose: To investigate how the concentration of vitamin C in Vitafresh powdered fruit juice changes over time once made into a solution. Justification: Vitafresh claims to contain “more vitamin C... than orange juice‚”[footnoteRef:0] which‚ with the upcoming winter season‚ would make it a suitable alternative to orange juice for combating sickness. The average daily requirement of vitamin C in an adult is 65-90mg per day‚[footnoteRef:1] so it is important to consider the quantity of Vitamin C

of the number of moles of a substance there are in every cubic decimetre (litre) of solution‚ written as moles.dm-3 of M for short. • In this experiment you will find out how increasing the concentration of the acid solution changes the rate of the reaction between dilute hydrochloric acid and magnesium metal. • As the metal reacts with the acid‚ hydrogen gas is produced and the metal dissolves. To get an estimate of the rate of reaction‚ the time taken for a small piece of magnesium ribbon
