spoken. His mother and father are also of Hispanic decent and both work in the education system. I planned a science experiment for Jesus which I decided to name‚ “Vinegar and Oil”. The experiment had Jesus mix oil and vinegar together to see if they will mix. The materials involved were one cup of vegetable oil‚ one cup of vinegar‚ one egg‚ and two bowls. The brisk air outside had us do the experiment inside his house. I prearranged and gathered all the materials needed so

friends. First you will need an egg. Then get a bowl. Also you will need vinegar. After you have all those here is what you will need to do. Boil the egg or eggs that you have. After you boil the egg let it set for at least an hour. Then set the egg in a bowl. When you have all that done just put vinegar in the bowl with the hard boiled egg ( How to make a bouncy egg). After letting the hard boiled egg set in the vinegar for three days take it out and let it set on a paper towel for a couple of

it can be declared that oxidation is faster in vinegar‚ than any other liquid. -Introduction: All of the people all around the globe thinking WHY do apples turn brown and what makes this happens. Well that was our main aim to this experiment conducted.Me and my group wanted to find out exactly what are the factors that increase or even decrease the amount of oxidation in (peeled)pieces of apples. This report presents the three liquids;vinegar‚tap-water and milk each of which includes peeled

come off. Naked eggs have their shells taken off with one simple ingredient everyone has. Vinegar. The vinegar acid inside the vinegar strips the shell away from the egg. The vinegar solutions dissolves the shell from the egg. Once the egg has been separated form it’s shell the only thing keeping the liquid goo inside is the thin‚ flexible membrane. Naked eggs are eggs with their shell removed after a vinegar soak revealing the membrane without cracking the egg. The membrane keeps the soft‚ gooey

solution‚ 50 milliliters of vinegar with 2 grams of sodium chloride‚ and the last conductive solution‚ 50 milliliters of distilled water with 2 grams of sodium chloride. In my first hypothesis I stated if I added sodium chloride to distilled water‚ than the overall conductivity will become more conductive than just distilled water‚ since the sodium chloride will break down into it’s respective ions. I also noted the solution will however be less conductive compared to vinegar and HCL also encompassed

The system in part 1 was to “pour the vinegar into the beaker that contains the baking soda”. The system in part 2 was to pour the vinegar in the plastic zip lock bag that contains the baking soda and then lock up the bag. The difference between the two is that in part 1 the experiment is out in the open‚ while the experiment for part 2

Vinegar Titration Lab Procedure: 1.) Obtain ~100 mL of NaOH. Record the molarity on the data table. 2.) Set up a ring stand with a buret. 3.) Place 5mL of vinegar in a 125 mL Erlenmeyer flask. Dilute the vinegar with 25 mL of water and add two drops of phenolphthalein. 4.) Fill the buret with NaOH. Record the initial volume of the buret in your data table. 5.) Titrate the vinegar sample until the first faint pink color does not disappear. 6.) Record the final volume of the buret in your data

Titration bre’ana March 1‚ 2013 Purpose: The purpose of this experiment is to determine the concentration of a solution of NaOH by titration with a standard solution of HCl. It was also the purpose to determine the concentration of a sample of white vinegar by titration with a standard solution of NaOH. Introduction: Using the method of titration is how the experiment gets to the conclusion of the concentration of a solution. When doing this experiment‚ measurement is very important to obtain the solutions
