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

of solutions and test their pH. Due to materials available pH strips were the only testing tools available. A table is setup to compare the strip color to its pH level. Four known solutions including bleach‚ lemon juice‚ soda‚ and baking soda were used. There was also an unknown solution in which the pH level was used to determine which solution it was. The pH scale is 1-14‚ a pH of 7 is neutral‚ less than 7 is acidic‚ and greater than 7 is acidic. Materials: * pH strips * 20 test tubes

pH and Chromatography Lab Report Kevin Rivera Biology Mr. Langley 2C 10/7/13 Introduction In this lab‚ of pH and Chromatography‚ in the pH aspect of the lab we are trying to figure out the pH level of certain chemicals by writing down of known solutions to find the type of unkown solution using pH standards. In the Chromatography‚ we are trying to separate the chemicals using water and a piece of paper. Methodology Materials: Safety Goggles pH indicator & pH indicator key

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

can reach a new pH level by interacting with soil. If water has a pH that is too high or too low‚ it can be life threatening to aquatic species and can corrode metal structures. After finding this out‚ I decided to test if water could reach an extreme pH just by interacting with soil around it. The question for this experiment therefore became the following. Will interaction with soil change the pH of water? I hypothesized that if water interacts with soil for three days‚ then the pH of the water will
