oxidising agent and reducing agent. Oxidation and reduction in terms of oxygen transfer Definitions • Oxidation is gain of oxygen. • Reduction is loss of oxygen. For example‚ in the extraction of iron from its ore: [pic] Because both reduction and oxidation are going on side-by-side‚ this is known as a redox reaction. Oxidising and reducing agents An oxidising agent is substance which oxidises something else. In the above example‚ the iron(III) oxide is the oxidising agent. A reducing

Determination of Iron by Reaction with Permanganate-A Redox Titration Purpose: The purpose of this experiment was to find the percentage of iron in an unknown iron oxide sample which could be determined through titration with a standard solution of potassium permanganate. Success in this analysis requires careful preparation and attention to detail. Performing this experiment also provides practice at titrations. The overall reaction is: 8H+(aq) + MnO4-(aq) + 5e- Mn2+(aq) + 4H2O Theory:

To misquote Monty Python what have the Ancient Egyptians ever done for us? Well‚ they’ve given us cake for a start! Roman and Greek history records cake-making but according to food historians it’s the early Egyptians who were the first skilled bakers. We’ve come a long way from there; what the Egyptians – and even mediaeval Europeans – called cake wouldn’t be recognisable to us as such today. Although the Egyptians wouldn’t even have called it cake; that’s a word that has been used in

Experiment 8: Synthesis of Adipic Acid Performed November 8th & 10th By Jennifer Seitz Organic Chemistry 344 Section 803 Fall 2011 Objective: The purpose of this experiment was to synthesize adipic acid from cyclohexanol via an oxidation reaction that was catalyzed by sulfuric acid. Purity of the product was assessed by measuring the melting point. Physical Properties/Structures: Name | Formula | Molecular Weight (g/mol) | Boiling Point (0C) | Melting Point(0C) | Density(g/mL)

So if there is not enough bacteria/Fungus/Yeast present in the batter‚ the maavu will not ferment or will not ferment properly. 2) If you are using chlorinated‚ Iodised water or bacteria free water or Ozonized water in your house‚ you will not be able to get proper fermentation in batter as all these chemicals have residual disinfection property.(except Ozone) . 3) If

Chemical agents have been around for many decades and have helped in the winning of wars but have also introduce a way to killing people that almost anyone can come up with and this has allowed terrorist organizations to have more ways to terrorize people throughout the world. Chemical warfare is really where it all began in World War One from the French. Normally we hear that the Germans started this but in fact the French did and the Germans were the first to study it with great detail and use

(2) In real world scenario‚ knowing the actual outcome of the action and acting accordingly is impossible. Rationality depends on the percept sequence to date and hence omniscience is not compulsory. As a rational agent should learn what it can‚ so that it can compensate partial/incorrect prior knowledge

okay love youAcidified potassium manganate(VII) is a strong oxidising agent so it can be used to oxidise substances. If a reaction occurs a colour change will be seen. Potassium manganate(VII) is deep purple and when it is reduced‚ it becomes colourless. Let’s take a look at some reactions involving acidified potassium manganate(VII). If a solution of potassium manganate(VII) is placed in a test tube and a light green solution of iron(II) chloride is added to the test tube‚ the purple colour of
