Question 1 Critique Dr. Honeydew’s report. Specifically‚ discuss what is missing and how the missing information should have been presented. First the PH measurements‚ Dr. honey dew does not explain how the PH device was calibrated or if the blood sample was added or mixed with anything prior to the measuring of the pH (like water‚ etc.). In regards to the absorption spectroscopy‚ the method by which the concentration was obtained is questionable. Was the concentration known before the experiment

Describe the difference between a mixture and a compound. A compound is a substance in which atoms of different elements are chemically held to one another. A mixture is a substance made by combining two or more different materials in such a way that no chemical reaction occurs. A mixture can usually be separated back into its original components‚ a compound cannot. Below are some examples of the differences between each. Compounds •Compounds are pure substances. •They are made up of two or more elements

lab is to determine the pH level of common household products. Introduction Liquids are either acidic‚ basic‚ or neutral. We are able to figure out which one it is based on properties‚ along with the pH. Acids taste sour‚ and bases taste bitter. Using the pH scale‚ you are able to know how strong of an acid or base a liquid is. High concentration of [H+] ions means that the liquid has a low pH. Therefore a liquid with a low concentration of [H+] would have a high pH. A pH of less than 7 represents

larger scale in industry. The aspects they may differ in are equipment‚ time taken‚ and many other things. In this report I will explain how and why laboratory and industrial scale differ using the example of preparation of aspirin. The first difference is that instead of weighing the 2-hydroxybenzoic acid on scales on a work bench in a beaker as you would in small scale‚ it is easier and safer to weigh it onto scales‚ in a plastic bag on the floor. This is easier and safer because the chemical is fluffy

Ph Lab Report Bryon Kim 123013 B(2) Biology Background information/Research PH paper (litmus paper) determines how acidic or how basic a substance is. The paper changes color accordingly to color code on the pH scale. The pH scale starts from 0 to 14. The lower the number the more acidic it is. Zero is the most acidic‚ and 14 is the most basic while 7 is the neutral number for example water. Examples of an acid is lemon juice or multi purpose cleaner. Examples of a basic substance is shampoo or liquid soap

Red Cabbage Indicator Aim – To create a pH indicator out of a red cabbage solution and to construct a basic pH scale to determine the pH of unknown solutions. Materials - • red cabbage leaves • 250 mL beaker • hotplate or Bunsen burner‚ tripod‚ gauze mat and bench mat • 10 test-tubes – equal size • test-tube rack Methods - Part A: Making the indicator 1. Tear up one or two red cabbage leaves‚ and place them in the beaker with enough water so that the cabbage is just covered. 2. Heat the beaker
