Billy Kong Chem&163 Lab Report 1 Analysis of Acids‚ Bases‚ pH and Salt Purpose: Explore various methods for determining the characteristics of acid/base solution. The goal of this experiment include the investigation of various acid/base indicators‚ calculating the change of pH with concentration‚ change of pH due to the addition of salt and different between strong and weak acids/bases. Safety and Disposal: Use extreme caution when handling concentrated acids and bases. Dispose of all

The effect of salt concentration on grass growth Abstract Our aim was to test the effect of different salinities on the growth of plants which what we did was measured different amounts of salt dissolved into 2 litres of water‚ watered the plant once with the salt water then for 9 days with pure ware. I found with my investigation that the less the salt‚ the more the growth of the plant. My aim was achieved by measuring the 5 fastest geminating (out of 20) and to measure the differences in growth

Compare and contrast the ways in which irony works in Oedipus and Macbeth‚ using specific examples from both plays to support your point. 4. Both The Wife of Bath and Lady Macbeth are strong‚ willful women who try to exert influence beyond the traditional role of women. Of course‚ one is a comic figure and one a tragic figure‚ so that makes them very different; explore a common practice or belief of the two

if an egg will float in salt water. The question is how much salt is needed to be added to the water to make the egg float. The problem is that no one knows how much salt is needed to make an egg float. Hypothesis It will take at least three teaspoons of salt to be added to the water for the egg to float. The reason why I think three teaspoons of salt will need to be added to water for the egg to float is because the egg a density that is lower than the density of the salt water.

Can salt change water’s density? I conducted an experiment using common household items to find an answer to my question. The procedure involves filling two cups with two hundred fifty milliliters of water. Then‚ mixing teaspoons of salt in water one at a time‚ until you’re able to submerge a raw egg in the solution and have it float up. My hypothesis is‚ salt does infact change water’s density‚ and if the egg floats it’s proof of density change in the water‚ because it must be less dense than the

Option A: Observation: During the winter‚ you spread salt daily on your driveway to melt the snow. In the springtime‚ when the lawn begins to grow‚ you notice that there is no grass growing for about 3 inches from the driveway. Furthermore‚ the grass seems to be growing more slowly up to about 1 foot from the driveway. Question: Might grass growth be inhibited by salt? My hypothesis is that the grass growth is being inhibited by salt. An average winter season last approximately five or

In the tale “The Wife of Bath‚” the Knight’s punishment fit his crime nicely. The knight’s crime was that he raped a maiden‚ for no other reason than to sate his sexual desires. While the law of that time called for his head‚ instead of executing him‚ King Arthur let the Queen decide what would become of him. King Arthur’s decision to let the Queen take over the Knight’s punishment makes sense because it is an issue that a woman would feel more strongly about than a man. However‚ the Queen takes

One Nation Under Drugs This problem has been going on for decades and still going on till this day. Should the U.S legalize every drug‚ would that be the answer? Do we continue with this twenty-five year plus war with drugs. The use of illicit drugs is illegal because of their intoxicating effects on the brain‚ damaging impact on the body‚ adverse impact on behavior‚ and potential for abuse. Their use threatens the health‚ welfare‚ and safety of all people‚ of users and non-users alike. I am against

Experiment 5: Percent Water in a Hydrated Salt Chemistry 1300 Instructor: 2/8/12 Abstract: The purpose of this experiment was to determine the percent by mass in a hydrated salt‚ as well as to learn to handle laboratory apparatus without touching it. The hydrated salt‚ calcium carbonate‚ was heated with high temperature to release water molecules. Gravimetric analysis was used in this experiment to determine the percent by mass of water in a hydrated salt. The hypothesis of this experiment was
