EXPERIMENT 5 REDOX TITRATION: TITRATION USING SODIUM THIOSULPHATE Objectives 1. 2. To prepare a standard solution of potassium iodate for use to determine the concentration of sodium thiosulphate solution accurately. To acquire the proper techniques of carrying out a titration. Introduction Redox titrations using sodium thiosulphate as a reducing agent is known as iodometric titration since it is used specifically to titrate iodine. The reaction involved is: I2 + 2Na2S2O3 I2 + 2S2O322NaI + Na2S4O6

Introduction Photosynthesis is a well perceived performance in which plants and other defined organisms use the energy of photons to convert carbon dioxide and water into a simple monosaccharide sugar known as glucose. Photosynthesis provides the fundamental energy source for essentially all living organisms. The most substantial and valuable byproduct of photosynthesis is oxygen‚ one of the most abundant elements living organisms depend on. Photosynthesis occurs in many organisms

The light reactions of photosynthesis contain two photosystems‚ two electron transport chains‚ and ATP synthase. These parts are embedded in the thylakoid membranes of a chloroplast. The photosystems contain a collection of chlorophyll molecules. Chlorophyll‚ which is the green pigment of leaves‚ absorbs light energy that excites electrons to a higher energy level. Energized electrons from photosystem I are passed down an electron transport chain and added to NADP+ to form NADPH. Electrons from photosystem

This lab was split up into two different experiments‚ using different variables in each. During the first section of the lab‚ we investigated the what the effect of light is on both photosynthesis and cellular respiration. Our hypothesis about this effect was that the cuvette representing ‘no light’‚ being covered in foil‚ would result in a yellow CO2 indicator fluid‚ meaning that there was a decrease in pH and a high level of CO2 was present. Additionally‚ we hypothesized that the cuvette that was

explain to you why photosynthesis is bad while helping Earth too. I will be giving you a few reasons to explain that photosynthesis is important. So even though photosynthesis can kill the plant‚ photosynthesis is important‚ because it helps grow food for omnivores and herbivores. Photosynthesis grows plants and trees‚ which produce clean‚ fresh oxygen. Photosynthesis helps us living organisms with lungs breathe. It helps us when plants go through the process called photosynthesis. During this process

Land Snail Practical Write Up Land snails are used as an archaeological methodology of reconstructing the past and are an environmental method that can fill in the gaps of other methods. For example‚ pollen and macroscopic plant matter study show the general change of a large area and only survive when waterlogged. Chalk lands are prime archaeological landscapes useful for study and land snail evidence can survive in them where other evidence cannot. Also‚ as oppose to representing a large scale

- Half a cup of water Procedure: 1. For this experiment‚ the independent variable is whether the balloon is filled with water or not. The dependent variable is what happens to the balloon when it is placed above the lit candle. This is determined by observing the balloon. The constants (control variables) are how much the balloon is inflated and the amount of water in the balloon. 2. Inflate the yellow colored balloon and tie it up. 3. Pour half a cup of water into the blue colored

BUS305-0804A-07 Concentration Ratio Economists use concentration ratio to measure the degree of concentration in a market‚ computed as the percentage of the market output produced by the largest firms (O’Sullivan‚ Sheffrin‚ & Perez. 2008). One of predominantly concentration ratio used is the Four Firm Concentration Ratio. Four Firm Concentration Ratio isthe percentage of total output in a market produced by the four largest firms. In considering a market with 20 firms and a CR of 20% ‚ I came up with
