Accuracy and Precision Lab Report By Connor MacFarland 10.23.2016 IBC 1 Question What is the difference between accuracy and precision and how can we demonstrate the difference? MATERIALS Pencil Notebook Paper 100 mL Graduated Cylinder 1 Gallon of water Ruler Unmarked Plastic Container 3 different kinds of Rocks of different sizes Triple Beam Balance PROCEDURE Estimating Lengths Procedure A piece of notebook paper was torn into 8 rectangles Without a ruler, a line was drawn which…

Claim, Evidence and Reasoning Graphic Organizer Question: Are Fat and Soap Different Substances? Claim: Fat and soap are different substances. Evidence (from your data) Solubility - Fat was soluble in oil. Soap was not soluble in oil. Fat was not soluble in water. Soap was soluble in water. Reasoning (why does the above piece of evidence support your claim?) The above piece of evidence supports my claim because it proves that in the same substance (H2O), fat and soap have different…

Measuring the mass of Iron in an iron sulphate tablet using REDOX titration Aim The aim of this experiment is to determine the mass of iron present in one iron sulphate tablet using REDOX titration under acidic conditions. Safety H2SO4: This is an irritant which may cause burns on skin and eyes; therefore care must be taken when handling this chemical. Protective gear (gloves, lab coat and safety goggles) must be worn at all times. If it comes in contact with skin or eyes, it should be…

Introduction: Kidney stones are an extremely basic urinary issue. Also known as renal calculi, kidney stones are characterized by their high occurrence and a high repeat rate. This issue results from the arrangement of insoluble salt stores in the urinary tract and inside the kidney. The rate of this issue has expanded in the course of recent years for reasons that are not entirely known, but have caught the consideration of numerous scientists. There are different types of kidney stones, each…

Part A Results We hypothesized that the iodine will diffuse into the bag, turning the inside a darkish blue/black color. We also hypothesized that glucose will diffuse out of the bag, forming a green color (after the Benedict’s test). This experiment was set up using a dialysis tubing bag, balloon clips, beaker, iodine, solution of 1% soluble starch and 15% glucose. The dialysis tubing bag was filled up with starch and glucose, leaving a pocket of air for diffusion of materials, and sealed…

Alka Seltzer contains the same three ingredients: 325 mg of Aspirin, 1000 mg of Citric Acid, and 1916 mg of Sodium Bicarbonate. Two of Alka Seltzer’s ingredients, Citric Acid and Sodium Bicarbonate (Baking Soda), were both placed into a beaker to see if both contents could cause a potential reaction. The final result was a non- occurring reaction. For a second test, both the Citric Acid and Sodium Bicarbonate were placed into separate, dry beakers. Afterwards,…

this experiment is to determine the type of chemicals that are inside the mislabeled bottles. Materials: • pH strips • 8 bottles of known chemicals: o silver nitrate o iron (III) nitrate o copper (II) nitrate o sodium iodine o sodium hydroxide o nitric acid o lead (II) nitrate o sodium carbonate • 8 bottles of unlabeled chemicals the same contents as known chemicals • 1 well tray Procedure 1. Place 7-10 drops of each chemical (known and unknown) into separate wells in the well tray. 2.…

The reaction between Propanone and iodine under acidic condition Aims To find the order of reaction with respect to propanone, iodine and sulfuric acid, thus proposing a rate equation. Find rate constant at various temperature and with the use of the Arrhenius equation, find the activation enthalpy of the reaction. General Method {For step by step guide of the experiment see preparation page} By using known concentration of aqueous iodine solution (0.000 moldm-3, 0.005 mol dm-3, 0.015…
