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

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

One common compound is Sodium Chloride (NaCl). Sodium Chloride‚ more commonly known as table salt‚ is used in cooking to season foods. Table salt is also used to make many chemicals‚ which make up the majority of the world’s production. Another common compound is Hydrogen Chloride (HCl). Hydrogen Chloride is typically combined with H2O to make hydrochloric acid. Hydrochloric

stories that contain the eight formal elements she identifies as prerequisites for the genre. Chief among them is the element of betrothal––or‚ as it is more colloquially understood‚ the “happy ending.” When considering Patricia Highsmith’s The Price of Salt‚ there is some room for debate as to whether the book can truly be called a romance. The novel details the courtship of two women in the 1950’s––Carol Aird‚ a wealthy homemaker in the midst of an ugly divorce‚ and Therese Belivet‚ a naïve‚ struggling

How does the relationship between salt concentration effect osmosis in the aquatic plant Elodea? Quantitative data From observing the cells under a microscope‚ we see that they are continuously moving and therefore are alive. We have observed that when the cells are in the 10% sodium chloride‚ the chloroplasts are positioned to the sides of the cell wall and the cytoplasm is more expanded. Cells in the distilled water are slightly smaller than the cells in the sodium chloride solution and

AIM The aim of this investigation is to explore the effect of different concentrations of bile salts on the time taken for the lipase enzyme to break down fat. BILE Bile is a brownish bitter alkaline fluid produced by the liver and made by the hepatocytes from water‚ bile salts‚ bile pigments cholesterol and phospholipids and stored in the gall bladder. Bile is directly connected with digestion. It is released sporadically into the small intestine (duodenum) which is part of the gut in order
