Analysis of Commercial Bleach Lab I. Purpose In this experiment‚ the amount of sodium hypochlorite in a commercial bleach will be determined by reacting it with sodium thiosulfate in the presence of iodide ions and starch. A solution of sodium thiosulfate of known concentration will be added to the bleach using a buret in a titration procedure. The disappearance of the dark blue color of the starch-iodine complex will signal the end point. II. Procedures Pre-Lab Questions 1. What is

Introduction: Generally‚ there are oxides of metals and non-metals. Metals burn in oxygen to form basic oxides while non-metals form acidic oxides. Structurally‚ they are covalent or ionic compounds. You are to

INTRODUCTION: Carbohydrates are the product that made up from carbon‚ hydrogen and oxygen. Carbohydrates are form by the combination of carbon dioxide and water molecules. The carbohydrates contain two specific functional group in it which is the hydroxyl groups and carbonyl groups.A reducing sugar is a type of sugar with is an aldehyde group.This means that sugar can act as a reducing agent.The procces of reducing sugar is isomerisation‚example of reducing sugar islactose

from natural‚ inbuilt motion of particles). Diffusion is an example of passive transport. Diffusion is the net movement of molecules or ions from a region where they are more highly concentrated to one where their concentration is lower. Figure 1 Figure 2 Diffusion is only possible because: All particles are constantly in motion due to the kinetic energy that they possess‚ This motion is random‚ with no set pattern to the way the particles move around‚ Particles are constantly

the based-catalyzed halogenation of the ketone that forms a trihalo ketone. First‚ the bleach is transformed into chlorine and hydroxide ions through the following reaction: Then‚ the hydroxyl is able to attack the rather acidic (pKa ~ 20) α-hydrogen of the ketone. This acidity is due to the stability of the resonance structures of the corresponding enolate ion that forms upon dissociation. When the hydroxide is able to subtract a hydrogen atom‚ a carbanion is formed. This carbanion is a very strong
