Experiment 20: pH Titration: Phosphoric Acid in Cola Drinks Post-lab Assignment or Report The post-lab report for this experiment is due at the beginning of the following lab period. Student notes for the lab will be available on the lab T-Square site. Learning Objectives Students will be able to... • Use a known mass of solid acid to determine an unknown concentration of a basic solution (this process is called “standardization”). • Execute a titration using good‚ reliable technique.

enzyme; this is where the magic happens. Substrate is what is being broken apart by the enzyme. In this case‚ the enzyme is catalase and the substrate is hydrogen peroxide‚ or 2H2O2. As the catalase and the substrate interact‚ the substrate is brought into the catalase and broken apart into water and oxygen. This process may be able to happen naturally‚ but the enzyme‚ catalase‚ speeds up the process.

Being a couch potato is what many of us tend to be when we are on a break or on a holiday but why not try to do something different and useful that could bring benefits to one’s self? Earning additional cash over the internet could be let us just say one of the most beneficial way to kill time. Making extra cash is not easy but it is definitely worth the effort because the extra cash could come in handy during the rainy days. Besides‚ it’s easier earning some side income through the internet than

Keegan Bauman Potato Lab Dr. Peano Block 1 Introduction: Potatoes are just your average food; they have been around for as long as the human race can remember. In this lab we will make them be a prime example of osmosis‚ which is a transport mechanism. In this lab the problem being tested was what environment affects the mass of the potatoes the most. The independent variable is the environments used salt‚ water and iodine solution. The dependent variable is the mass of the potato after being

Potato Cell Cytoplasm Composition PURPOSE: To determine the concentration of salt in the cytoplasm of potato cells HYPOTHESIS: Increase in salt concentration results in a hypotonic solution where the mass of the potato increases due to the movement of water into the cell. On the other hand‚ decrease in salt concentration results in a hypertonic solution where the mass of the potato decreases due to the movement of water outside the cell. MATERIALS: Potato Forceps Stopwatch Scalpel Test

concerned with Irish history. Looming over the scene depicted is the spectre of the potato famine that afflicted Ireland from 1845-49. The potato crop‚ staple for the Irish‚ failed‚ and with cataclysmic results. About half the population of three million died‚ while a million people emigrated – many to America. The first section of the poem is written in alternately rhymed quatrains that describe a rural scene of potato digging that is clearly in progress much later than a similar scene around the time

Reaction of catalase with hydrogen peroxide AIM: I aim to find the rate of reaction between catalase and hydrogen peroxide. Enzymes such as Catalase are protein molecules that are found in living cells. They are used to speed up specific reactions in the cells. Each enzyme just performs one particular reaction so they are all very specific. Catalase enzymes found in living cells e.g. in yeast‚ potato or liver‚ speed up (in our case) the breaking down of hydrogen peroxide. The lock and key analogy…

Global Variations in the Potato Crisps and Potato Chips Market It’s fair to assume that consumer snacking habits are likely to differ from country to country‚ particularly across different regions and cultures. A clear example is the consumption of potato crisps / potato chips which can be seen in the bar chart below. 86% of consumers throughout the USA and France consume potato crisps / potato chips closely followed by 84% of GB consumers. On the other end of the scale is the Chinese market
