Percent Composition Report Hypothesis : By using seperation techniques properly‚ the 3 substance such as; water‚ sand‚ and salt can be seperated and the percent composition of each substance. Which will then be calculated theoritically and after comparison with the actual result‚ the accuracy of the 2 result can be found. Aim : The aim of this experiment is to compare the gravimetric result of the original mixture and the separated substance. The other objective is to calculate each percent

Investigation – Storage conditions of Bleach & it’s relation with temperature. Title/Research Question: ‘How does temperature effect the concentration of chlorate ions in bleach?’ Aim: The aim of this experiment was to investigate the optimum temperature storage conditions of bleach’s stored at different temperatures. Introduction: Chlorine bleaches are made by dissolving chlorine in sodium hydroxide solution. They have a number of uses as they are used to remove colors‚ whiten or disinfectant

An investigation to show how the rate of reaction between hydrochloric acid and sodium thiosulphate is affected by the concentration of the acid Simple Procedure Place a conical flask on a piece of paper with a cross on it. Add hydrochloric acid and sodium thiosulphate‚ and record the amount of time taken for the cross to disappear through the solution from the top of the flask. Record this time and repeat this for different concentrations of hydrochloric acid. Fair Test The variables in

Red Cabbage Indicator Indicators are chemical compounds that can be added to a solution to determine whether it is acidicor alkaline. The indicator will change colour depending on whether an acid or an alkali is added. The colour in red cabbage (it is a pigment called an anthocyanin) makes a very good indicator. Acids and alkalis Acids have a sour taste‚ like vinegar (which contains ethanoic acid) and lemons (which contain citric acid). Alkalis are substances that react with acids and neutralise

The Cabbage Indicator Experiment My hypothesis for this experiment is if I put an acid or a base in to a neutral then it will change colors. My hypothesis was correct in assuming that it would change colors with different substances or mixtures. If I put an acid or a base in to a neutral then it will change colors. The red cabbage indicator did change colors. Greens for bases and reds and pinks for acids. An alternative hypothesis for this could be “If the red cabbage indicator is purple then adding

Sandeep Voleti- Period 4/5 Honors Chemistry Titration Lab Writeup Introduction Titration is a method‚ which is meant to find the concentration of either an acid or a base by adding a measured amount of it to a known volume and concentration of an acid or base1. Titration starts with a beaker or Erlenmeyer flask containing a very precise volume of the known concentration solution and a small amount of indicator‚ which is put underneath a burette containing the solution with unknown concentration1

School of Chemistry @ Pietermaritzburg University of KwaZulu Natal Chemistry 310 Substitution reaction of Molybdenum Hexacarbonyl: the use of infrared spectroscopy as a structural tool in metal carbonyl chemistry. Abstract The synthesis of isomer A and B of [Mo(CO)4(PPh3)2] were prepared from molybdenum hexacarbonyl‚ sodium borohydride and triphenylphosphine with a % yield of 79% and 8.5% respectively. Two isomer was identified using IR spectra and from isomer A four C≡O stretching
