chloride solution to the experimental Petri dish. Results were observed and recorded. Results In station 1 when the acid was added to the experimental Petri dish the bioluminescence of the powdered firefly lantern started to dim and once the base was added the lantern began to brighten up again. The controlled Petri dish remained bright during all four of the experiments. The results are as shown in Table 1. In station 2 after the experimental Petri dish was taken out of the fridge and

maalox Lab There were five main purposes of the maalox lab that we wanted to accomplish. This included producing two precipitates, classifying reactions, providing visual evidence on a chemical change, using pH indicators to identify bases and acids, and describing what happens during neutralization. In the lab, there were two reactions that occurred. The reaction happened when there were reactants that combined to create end products. In the first reaction, the reactants used were alum and ammonia

Water. It is one thing that every person on earth relies on to live. Its essential to all living things in order to survive. Humans would only be last to last days without it. It is crucial to our diet and our health. In fact, there are many different kinds of water. There are different types of water for example, alkaline, tap, spring, natural, filtered and the list could go on. But water is water, right? Wrong, not all water is the same. In fact different brands of water that we are so used to

Science Fair Outline Have you ever took a sip of water, only to find it disgusting and hard tasting? It was probably because there was too much chlorine or the pH level wasn’t good. In my experiment, I am going to compare ten different kinds of bottled water to tap water by testing for pH, chlorine, and a few other measurements so you can find out what to drink when you’re thirsty. I am going to test the waters by dipping testing strips into the water and comparing those results to those of the

This year, the science fair project and experiment chosen was meant to test the effects of various gases on water, to experiment if different gases would change the pH of liquid solutions. To carry out the investigation, three gases, nitrogen, oxygen, and carbon dioxide, were dissolved into 100 mL of distilled water each. While the gases were being added to the water, there were fast-paced bubbles speeding around because the gas was present in the bubbles. Once the liquid was saturated, it was,

Does the amount of active ingredient in different types of tablets decrease or increase per milligram after its expiration date? Overtime, the concentration of acid in a low dose aspirin tablet increases, as the concentration of acid in a high dose aspirin tablet decreases. However, due to various experimental errors, the claim is not a strong and compelling one. What is assumed to have happened is that both low dose aspirin tablets and high dose aspirin tablets increase in concentration of acid

important? pH is a good indicator of the lakes healthiness.pH is a way to measure how acidic or how alkaline a body of water pH scale goes from 0-14 a zero is the strongest acid.  A reading of 14 would be the strongest base. Pure water is considered neutral-rather an acid or a base with a pH reading of 7 Indicator measure the pH in watersheds to determine whether the water is acidic/neutral, or base.Most living things have adapted to a life in water with specific pH. If the pH changes the organisms

The objective of this experiment was to determine the identification of the unknown copper (II) salt. The unknown salt was found to be copper (II) bromide. A calibration curve for copper (II) sulfate pentahydrate in Trial 1 was found by measuring the absorbance of the four different dilutions and the original solution as shown in Table I. The concentration of each solution was then calculated by multiplying the amount of moles in the original solution by the amount of original solution used in L

Introduction On Thursday, October 6th, 2016 I studied the Conodoguinet Creek in Cumberland County, PA. I went to the creek to study the health of the creek itself (Phosphate levels, Nitrate levels, Dissolved Oxygen levels, pH levels, and Alkalinity levels). My hypothesis was: If I test the Conodoguinet Creek for signs of acid rain, eutrophication, or other types of pollution, then the tests will reveal that the creek is healthy and has very low levels of pollution. Eutrophication, is the excessive

1. Ion exchange chromatography is a technique, which separates a mixture of amino acids based on their produced charge. Isoelectric point is a pH where the given amino acid has a no charge thus; produces a neutral structure. With a pH above the isoelectric point will cause the amino acid to be deprotonated and thus; produce a negative charge where as a pH lower than the isoelectric point will cause the amino acid to be protonated and thus; hold a positive charge. 2. In the experiment a cation exchange
