Lab 1: Determining the pK a of PNP PNP or paranitrophenol is an organic compound that undergoes changes when the pH is manipulated of the solution. PNP is also an acid/ base indicator. The compounded starts off as internal conjugated ring with the hydroxyl group and the nitro group single bonded to the aromatic ring. This occurs at the pH of 5. At this point the aromatic compound is colorless and is in the ultraviolet range. However‚ as the pH begins to increase the hydroxyl group deprotonates

Lab 1 – Measurement of Space and Time Anthony Lucci Lab Partner: Amy Hayes Question 4: Both the height and diameter of the cylinder were taken to find the volume; five times for both measurements. Vernier calipers were used to get these measurements by clamping the cylinder between the jaws of the calipers. By looking at the mark of the zero‚ in relation to the main scale‚ the line best lined up with a line from the main scale was taken down. Getting

Maintaining Focus in Despair Class: GS2745 Date: 09/23/13 Unit#: 1 Lab#:1 I can recall a time where I had to maintain focus and persistence in spite of obstacles that I was facing at the time. This is in fact‚ in recent history as I was going through a combination of events that seems to have come out of nowhere. I am a full time student‚ and set to graduate in two quarters. Around the end of Spring quarter and beginning of the Summer Quarter‚ I lost my job. In addition to that‚ I was

Journal Questions 1. Make a hypothesis about how you think the two species of Paramecium will grow alone and how they will grow when they are grown together. (Make sure you understand what a hypothesis is before you address this!) Each paramecium growing on its own will be able to grow and flourish because there is nothing stopping it or competing with it. It will be able to grow to its full capacity. When there are both parameciums growing together; one paramecium‚ the stronger of the two

In this lab we tested to see if the amount of sunlight exposed to the basil seed‚ would affect the growth. The null hypothesis for this experiment was that there would be no statistical difference between the green‚ yellow‚ and red basil seeds’ growth. Three alternate hypotheses are: If we expose the green seed to 48 hours of sunlight and the yellow seed to 24 hours of sunlight‚ then the green seed with grow more than the yellow. The opposite of this hypothesis would alternate 2. Another alternate
