Project 10- Multiple Oxidation States Oct 27 2020 Lab B01-A Introduction: The purpose of this lab was to synthesize Tin (II) iodide and Tin (IV) iodide. The Tin(II) iodide compound was formed by reacting the element of Tin with concentrated hydrochloric acid to first form tin(II) chloride and then underwent a double decomposition reaction with the solution of zinc iodide. Tin(IV) iodide was formed by heating tin in the presence of iodine. The two main oxidation states for tin are +2 and ...

Biochem - 1st Year All amino acids contain a central carbon, a side chain (R group), an amino group and a __________ group. - correct answer Carboxyl Amino acids can undergo a proton transfer, thus giving both a (+) and (-) charge. This molecular state is called the ________. - correct answer Zwitterion Amino acid that are unable to be synthesised from biochemical pathways within a cell have to be consumed through dietary intake. These are called _______ amino acids. - correct ans...

A Level Edexcel Chemistry - Topic 3 - Redox 1/I Fully updated notes providing drop down answers to self made questions designed from numerous textbooks and exam mark schemes. During my revision, I created these drop down questions and answers by extracting the key information needed to achieve top marks in exams. I achieved a high A* using only these notes. Notes for all other topics have been released on my page :) Hope I can help!

Aldehydes differ from ketones in their oxidation reactions. Aldehydes are easily oxidised to carboxylic acids on treatment with common oxidising agents like mno2
