Procedure: What you need: -Four raw eggs -Four cups of white vinegar -beakers/cups for the eggs What to do: 1. Put the 4 eggs in each cup with one cup of vinegar. Let that sit for 24 hours. This will make the egg shell come off or dissolve. If the egg shell is not off‚ put the egg in fresh vinegar. Then‚ carefully wash the egg in water and measure each egg using a string to measure length and width using cm. Then put each egg in either‚ vinegar‚ corn syrup‚ a thin solution‚ and one of your own. 2.

osmosis and diffusion. In this experiment I began by calculating the volume of a fresh chicken egg. Then to determine the effect of osmotic pressure change on a cell I soaked the raw chicken egg in vinegar for 24 hrs‚ and measured the volume of the egg after the shell had been dissolved by the vinegar. The egg was then submerged in corn syrup for 1-24 hrs‚ then measured and recorded the new egg volume. Finally the egg was submerged in water for 1-24hrs‚ again the volume was measured and recorded

Title: What is the effect of acidic substances on the mass of curd formation? Purpose The purpose was to determine if lemon juice or if vinegar produced more curds. Background Information Curds were formed by a change in pH or by a change in temperature of the milk. Milk has a pH of 6.6 approximately‚ and at this pH the proteins were able to repulse each other‚ creating a negative charge. One of the proteins in milk is called casein‚ which when an acid of a lower pH than 6.6 was added‚ it will

Langlis‚ AP Chemistry C-D 9/24/2017 Purpose: Determining the precise concentration of vinegar through titration using a standard solution of Potassium Hydroxide (KOH) (aq) Background: Vinegar is a solution of acetic acid (CH3COOH) in water. The concentration of acetic acid in Vinegar is written as a Molarity (mol/L). In this experiment‚ titration is used to determine the concentration of acetic acid in vinegar. Titration is an experimental technique for determining the concentration of a solution

objective of this experiment is to demonstrate osmosis by using an egg as a model. In order for this to happen the vinegar will make the eggs shell disappears. The reason for this is because vinegar has acetic acid and the shell has calcium carbonate‚ when these come into contact it produces carbon dioxide. This is the reasoning for the little bubbles when the egg is first put into the vinegar. After the shell discinigrates it will become rubbery from the acetic acid‚ at this point the egg could very well

to corrode or rust faster? I have decided to base my experiment on four different types of metals and four different liquids. I will be using a penny‚ nail‚ paper clip and a needle as my four metals. My four liquids will be vinegar‚ beach‚ lemon water and salt water. To get started‚ the metal contents should be established. Today’s pennies are mostly made of zinc with a thin layer of copper overcoating. A nail is a form of carbon steel or black

respectively): 1. Add roughly 200ml of distilled vinegar in plastic bottle of narrow neck with capacity of at least 500 ml. 2. Add ~ 1 table spoon of baking soda (Sodium bicarbonate) into a balloon (it works the best if the balloon is already stretched out). 3. Tie the balloon onto the top of bottleneck. Be careful not to add baking soda into the bottle yet and make sure that the balloon is flattened. 4. Quickly add baking soda into the bottle (vinegar) and observe carbon dioxide production. 5.

Abstract The purpose of this experiment is to determine the concentration of acetic acid in vinegar by using 0.1 M HCl and NaOH solution. By performing three titrations to determine the concentration of the base‚ the concentration of the acid was determined to be 0.600 M. It was possible to determine its concentration by standardizing the sodium hydroxide solution used for the first three titrations and by using phenolphthalein to indicate its equivalence point. In conclusion‚ although there were
