Sodium hydroxide

Method: A filtration apparatus was set up. Solid iron(III) chloride hexahydrate was dissolved in water. In a separate container, sodium acetate trihydrate (NaC2H3O2 x 3 H2O) was also dissolved in water. Sodium acetate trihydrate was then added to iron(III) chloride. 2, 4-pentanedione (C5H8O2) was dissolved in methanol; it was then added to the iron(III) chloride/sodium acetate solution. The product of this mixture was filtered, and the precipitate

Want to try out something strong and worth your time of brewing? Then, the Belgian Dark Strong ale will be the great choice to brew. This recipe yields about 6 gallons of beer. Main Ingredients 8 pounds of Belgian Pilsner malt 4 pounds of Belgian Pale malt 2 pounds of Marris Otter malt 1 pound of flaked oats 1 ounce of Magnum hops that contains about 13.6% of alpha acid 1 pound of Dark Candi Inc. D Belgian candi syrup, for 60 minutes 1 pound of Dark Candi Inc. D2 Belgian candi syrup, for 60 minutes

In this experiment, we extracted caffeine from a tea bag. First, we had to convert protonated caffeine in tea leaves back to the free base form. So in a 30 mL beaker, we added 30 mL water and 2 g sodium carbonate and after boiling the water we immerged a tea bag in the hot water for about 5 minutes. After the tea bag was slightly cool we squeezed the tea bag to remove all water and caffeine using a funnel and back of a test tube. After that, we again brought the water to boil and immerged another

organic solution with 1 mL of Magnesium Sulfate to ensure that only organic material is present in the solution. If two layers form again, extract the organic layer and place it in a new, clean 10 mL flask. Then, dry the organic solution with anhydrous sodium sulfate, and extract the dried solution using a filter pipet into a clean vial. Characterization:

In this lab experiment our main focus was to get skillful in using tools such as the metric ruler, balances, thermometer, and graduated cylinder to capture measurements of length, mass, temperature and volume. Additionally, this lab helped us to become more familiar with the uncertainty of measurements, as well as becoming efficient with rounding our measurements to the correct numbers of significant figures. Our results are measured consistently with rounding to the closest answer we could possibly

As an employee for a company that processes silver ore, you are developing a method for recovering silver metal. The ore sample is crushed, dissolved in strong acid, and treated with a solution of sodium chloride to isolate the silver as silver chloride. The precipitate is dried and collected for further processing into silver metal. You test the procedure by dissolving 10.00 g of ore in an aqueous acidic solution and diluting the solution with water, so that the final volume is 1.0 L. To the

Seperating a Mixture Materials an empty 2 liter bottle measuring cup tape coffe filters nylon magnets scissors nails water salt oil sand STEPS. 1. I started by pouring all of my ingrediants (nails,water,salt,oil,sand) into the measuring cup and wait for everything to settle. 2. I removed the nails by using my magnets and then placed them aside and left the rest of the mixture in the measuring cup. 3. Next I took my empty 2 liter bottle and cut off the bottom. I cut about 2 inches from the bottom

Determining Volume The first expiriment for my volume project was determing the volume of a solid. For this expiriment I used a metric ruler and a small block of wood. I began with recording the measurements of my piece of wood. The width was 10.3cm, the length was 17.5cm, and the height was 1.4cm. My next step was multiplyig all of my measurements together to find the volume and after doing so, I got 252.35cm3. The second part of my project was determining the volume of a liquid. For this

In day 2 of the experiment in step 1, two millitliters of 2% silver nitrate solution in ethanol were placed insix test tubes. Two drops of the six alkyl halides were added to the test tubes. The alkyl halides included, n-butyl chloride, sec-butyl chloride, t-butyl chloride, n-butyl bromide, allyl chloride, and chlorobenzene. Once the alkyl halides were added, the contents were swirled, and left alone to react. The t-butyl chloride, n-butyl bromide, allyl chloride, and chlorobenzene all reacted and

chemical substance was stolen from the chemical storage room. There were 4 chemicals. Sodium bicarbonate, calcium carbonate, sodium nitrate, and finally sodium thiosulfate. As a forensic lab technician, we analysed each chemical. We had to determine how each chemical reacts with water and acid. Our main goal was to figure out who stole the chemical. We had to investigate many chemicals. The first one was Sodium bicarbonate. We tested the chemical and the results were that the form was amorphous
