titration by twisting the lever on the side of the buret until small drops come out. Keep swirling the solution until a pink color is visible throughout from the phenolphthalein. 8) If over titration occurs ask the teacher for further instruction. 9) Write down the final volume in the NaOH buret 10) Subtract the final volume of NaOH from the initial volume. 11) Repeat this process at least twice more.

Speaker on Solar Cells — Outside event October 24‚ 2017 Today I attended a talk curated by the Ithaca College Chemistry Department by Kathleen Sampson‚ a Ph.D. Candidate at the University of Toronto. Sampson presented about the intersections of chemistry and engineering in regards to innovating new materials to produce solar energy. Sampson discussed organic solar cells‚ a type of solar energy technology that converts sunlight into electricity using “Earth-abundant‚ carbon-based materials” according

Title: Grip Strength and Muscle Fatigue I. Purpose/Hypothesis: In this lab the subject will grip on a scale that measures the amount of force being put on it. We will observe the change in hand strength during continuous grip over time. Then we will also measure hand strength during rapid‚ repetitive gripping. I believe that hand strength will weaken during a continuous grip more than if you were to keep a repetitive grip. II. Procedure: 1. Connect the Hand Dynamomenter to LabQuest and select

The Virtual Lab – ELISA Test Lab: Immunology 09/04/2013 Instructors: Dr. Charlie Wilson Written by: Dipen Patel I. Objective: The purpose of the lab was to learn the procedure of performing an ELISA test to determine whether a particular antibody is present in a patient’s blood sample. ELISA is an abbreviation for “Enzyme-linked Immunosorbent Assay." II. Introduction: The interaction of antigen and antibody outside the body can be used to determine if patient

This article from The Onion addresses the way that today’s scientific research is conducted and makes fun of how the source of funding for an experiment can influence its results. Interpreted plainly‚ the article claims that a new step has been added the scientific method: after a hypothesis is made‚ funding must be found. Then‚ based on who is funding the research and the sponsor’s desire‚ researchers must then align their study so it gets the results the funders want. The organization in charge

Alengasa‚ 2009). Mild cases of athlete’s foot are improved by keeping the feet dry and using foot powder especially between the ties and changing socks frequently. Foot powder relieves itching and absorbs moisture on the feet. It also soothes irritated skin and prevents foot odor by controlling odor-causing bacteria. Applyinf foot powder will lessen the presence of bacteria especially if the powder contains Calamansi. Calamansi could be a good antibacterial agent in removing bacteria because of its acidic
