EXPERIMENT 8 QUANTITATIVE DETERMINATION IODOMETRIC TITRATION OF COPPER CONCENTRATION IN AQUEOUS SOLUTION B Y RESULTS AND DISCUSSION Considered as moderately weak oxidizing agent‚ Iodine was used for the determination of strong reductants. Standard iodine solutions were found to have smaller electrode potentials as compared with the other oxidants‚ gaining them the advantage of imparting a degree of selectivity essential in the determination of strong reducing agents amid the presence

Neutralization experiment AIM:- To investigate how heat is given out in neutralizing sodium hydroxide (NaOH) using different concentrations of Hydrochloric Acid. Background Information:- Substances that neutralize acids are called alkalis. An acid is a substance that forms hydrogen ions (H+ ) when placed in water. It can also be described as a proton donor as it provides H+ ions. An example of an acid is hydrochloric acid (HCl)‚ Sulphuric acid (H2SO4) etc. An alkali is a

My proposed concentration in the Creative Arts Diploma would be musical theatre. I have been doing theatre for most of my life‚ and i feel it has really impacted me as a person. Studying musical theatre is very important to me because I feel as I can grow as a learner and as a performer by taking CAP. The CAP program s very intriguing to me and I hope to get better at musical theatre wise‚ and I also feel by being in CAP‚ there are some skills that will help me in school life. For example‚ project

amylase which catalyses the breakdown of starch to produce sugars such as maltose (Sherwood‚ 2013). When testing the effect of the salivary amylase concentration‚ we observed that the solution containing the most saliva (3ml)‚ become colourless faster than the solution which contained the least saliva (1ml). This proves that an increase in enzyme concentration (increase in saliva)‚ will cause an increase in the reaction rate (Bennett and Frieden‚ 1969).

confirming Beer-Lambert’s Law was a successful method in determining the molar concentration of a sample within a composition that is unidentified. Absorption spectroscopy is used in order to determine the ε value; ε was calculated to be .0566. Introduction: The purpose of the Absorption Spectroscopy experiment is to evaluate the reliability and accuracy when using Beer-Lambert Law to determine the concentration of a specific sample within a mixture solution. The number of electrons being

that mobile phones should be banned First‚ mobile phones will distract the student from paying attention to the class. For example‚ if you are holding phone in your hand while the teacher explain something important‚ you can’t understand what he say because you are busy with you phone and that’s wrong thing to do. However‚ it can also make you forget everything in the class because you were playing or chatting in the class. As a result‚ don’t be surprised if your grade become low or you
