Formal Lab Report | Chemistry | | Student name: Sara Hattar Grade: 10 ”C” | | Teacher: Christine Ziadat | | | Title: Investigating the effects of changing the concentration of an acid on the rate of reaction between HCl and Magnesium. Aim: In this experiment we are going to see the effects of using three different concentrations of HCl when added to Magnesium metal on the rate of reaction. Hypothesis: If the concentration of the acid increased in reaction between HCl (the acid)

Lab 1: Alkene Addition: Bromination of (E)-stilbene I. Introduction: 1. The purpose of the experiment was to perform an electrophilic addition reaction by using pyridinium tribromide to brominate (E)-stilbene and to identify whether it formed the meso- or racemic product through melting point analysis. 2. This is the mechanism for the bromination of (E)-stilbene. However‚ this is the mechanism for Br2 and in class we us Pyridinium Tribromide instead due to the difficulties associated

Identification of its structure by NMR spectroscopy revealed that it was 2-(4-methylbenzoyl)-1-naphthyl N-(tert-butyl)carbamate (4a). Next‚ in order to improve the yield of 4a‚ the effects of different solvents‚ reaction temperatures and times together with the molar ratio of the reactants were examined in this model reaction‚ for

Potato Osmosis Biology SL - ATh INVESTIGATION “Potato Osmosis” INTRODUCTION Osmosis is a process that occurs at a cellular level that entails the spontaneous net movement of water through a semi-permeable membrane from a region of low solute concentration to an area of high solute concentration in order to equalize the level of water in each region. Involved in this process are hypotonic‚ hypertonic and isotonic solutions. A hypotonic solution is one with a lower osmotic pressure‚ indicating

hydrochloric acid will change the mol of reactant. It will be affecting the rate if it becomes limiting reagent. I am always going to use 3.00g of calcium carbonate weighed on the electronic balance. Ensure calcium carbonate is pure supply‚ not contaminated. Surface area of CaCO3 The surface area of calcium carbonate should be kept constant. Different surface area of calcium carbonate will change the number of collisions between particles‚ as the calcium carbonate reactants have different exposed area of
