Sodium hypochlorite

Much of the workflow for ceramics production remains the same over the many years this art form has been practiced. When centuries ago, a potter starting the process workflow of producing a ceramic mug (or more likely a jug), he would go to a river bed and collect the clay. Now, Angel Pottery’s supplier is currently a clay supplier in Amherst, Massachusetts. In this supplier’s factory, they use mixing augurs to produce the raw material clay. From factory to home factory, the clay bags are…

It simply used, a test tube, meniscus, and pipette. Then a 15 cm long sprig of elodea was placed in the test tube, after 2 cm was cut from the stem. The test tube was the filled with sodium bicarbonate solution, with 3 cm left at the top of the test tube. The volumeter stopper was then placed in the test tube. The stopper was the adjusted so the solution extended 1 to 2 cm into the pipette. The volumeter test tube apparatus was then…

Purpose: The objective is to separate the heterogeneous mixture of salt, iron filings, and salt into each pure form using filtration, evaporation, and magnetism. Background: When separating a mixture, preferably to separate a mixture that includes a soluble liquid and a insoluble solid, filtration is the best because solid molecules are bigger than liquid molecules. A filter contains pores that are small enough to let small partials though the pores while holding back the larger particles.…

What’s in This Toothpaste is a formal and informational essay. Bodanis’ essay has an overall explicit thesis, which is to be aware of ingredients in your toothpaste hence the title “What’s in This Toothpaste?” Some background information for the reader would be that Canadian laws require manufacturers to label all ingredients on a product (Bodanis, 10). Bodanis starts by listing the three major ingredients; water, chalk, and titanium dioxide. Next, he describes other enhancing ingredients in the…

First, 1.32 g of isoborneol was mixed with 1.00 mL of glacial acetic acid. The solution was heated to 50° C while 1.70 mL of NaOCl added. Then 15.0 mL of NaOCl was measured into a separatory funnel and added dropwise to the solution for 10 minutes. The flask was sealed while heating and stirring continued. NaOCl in the solution was tested every five minutes using starch-iodide paper for 30 minutes. After 10 minutes, 2.0 mL of NaOCl was added. A total of 6.0 mL of NaOCl was added over a 20 minute…

exhibits physical properties without undergoing any changes in its chemical composition. Different materials have different melting points and thus, they can be identified with ease. Clearly, it was observed that the residue comprised a combination of sodium bicarbonate extracts once the ether had evaporated from the hood. How to Remove Water that was dissolved in Diethyl Ether Water that was dissolved in diethyl ether can be removed using a commercial drying agent such as MgSO4 salt. The…

There are several physical and chemical methods, of which the simplest method involves the reduction of the metal salt AgNO3 by NaBH4 in water. Wiley and his coworkers synthesized three different shapes of silver nanoparticles using chemical method, in which ethylene glycol used as both solvent and reducing agent [5]. This group synthesized cubic silver nanoparticles by reduction of silver nitrate (AgNO3) with ethylene glycol in the presence of Polyvinylpyrrolidone (PVP) and HCl. After synthesis…

Question: How does functional groups on ethane impact the exothermic energy released during the combustion of the compound? Hypothesis: Equipment: Thermometer Ethane Ethanol Ethanoic Acid Fire and a skewer Weighing scale Ceramic Container 400ml beaker Aluminum foil Lab coat apron Safety goggles Retort stand and ring clamp Procedure: Wear your lab coat / apron and your safety goggles. Prepare 100ml of water into a beaker then cover it with an aluminum sheet. Poke a hole through the…

Task 3: Explain standard solutions and at least 3 different types of titrations that are used in industry and compare these to titrations in the lab. Standard Solutions & Titrations A standard solution is a solution of a known concentration. Standard solutions are made by dissolving an accurately weighed mass of a solid in a known volume of a soluble solvent using a volumetric flask. Method • Firstly, you would need to calculate the mass of the NaOH that you are going use. • Next you…
