TITLE OF EXPERIMENT 2 : DILUTION 2.1: OBJECTIVES Upon completion of this experiment‚ students should be able to: 1. determine the concentration of coloured solution such as FeCl3 by using dilution and colour differentiating (colorimetric) techniques. 2.2: INTRODUCTION Concentration can be expressed in many different ways such as percentage volume and percentage weight etc. In laboratory‚ normally concentrations were expressed as molarity and normality. Molarity is the

Introduction In this lab‚ the purpose was to verify Hess’s Law. Four main topics were covered during this experiment including enthalpy of reaction‚ heat of formation‚ Hess’s Law‚ and calorimetry. The enthalpy of reaction‚ ΔHrxn is the heat or enthalpy change for a chemical reaction. The energy change is equal to the amount of heat transferred at a constant pressure in the reaction. The change represents the difference in enthalpy of the products and the reactants and is independent of the steps

OLD COINS TURN TO GOLD DESIGN: Problem or Research Question: How does zinc effects the color change in a copper penny? Hypothesis: If copper and zinc comes together‚ then it will form brass‚ which gives gold color to copper penny. Variables: There were no variables at this experiment PROCEDURES: Materials: Zinc (SN) filling‚ 3M NaOH solution‚ Copper penny‚ tongs‚ Hot plate‚ 100 ml beaker‚ 250 ml beaker‚ Bunsen burner‚ Water‚ Spoon. Procedure: First‚ we turned on the hot plate.

Lauren Sullivan Plants Imperfections Abstract The purpose of this experiment was to plant different crosses and observe the different phenotypic ratios the plants present. The procedure of this experiment was plant six different crosses and water them correctly so that we could observe the different phenotypes and compare them to Mendel’s proposed ratios. Mendel‚ who had studied peas‚ did a similar experiment and came up with specific ratios that a monohybrid and dihybrid cross should show. His

Investigation Investigate the amount of heat evolved when magnesium reacts with dilute acids. Planning What I am going to do I am going to find out how much heat is given out when magnesium reacts with a variety of dilute acids. In order to make comparisons between the acids‚ I shall use my results to work out how much heat would be given out if 1 mole of magnesium reacted with an excess of each acid. The acids I shall use are hydrochloric acid‚ sulphuric acid‚ nitric acid and ethanoic acid

to understand the difference between heat and temperature‚ and make some quantitative measurements concerning both. We used the technique called calorimetry to measure the specific heat. Calorimetry‚ it is the process of measuring quantities of heat. The purpose of the calorimeter is to prevent heat lose to the surroundings (Leybold 2000). Calorimetry is literary “the measurement of heat content”. In this experiment‚ a certain amount of hot water‚ at a particular temperature‚ is poured into the
