Sodium sulfate

Questions What will happen when zinc is placed in copper (II) sulfate? What will happen when copper is placed in copper (II) sulfate? Prediction It is predicted that when you place zinc and copper (II) sulfate a reaction will occur, resulting in a precipitation. The prediction about the copper (II) sulfate and copper is that nothing will happen. Hypothesis It is hypothesised that when zinc is placed in aqueous copper (II) sulfate, a single displacement reaction will occur as the zinc is in its…

test tube A, the reactants are copper sulfate and magnesium. Magnesium is an element and copper sulfate is a compound. In a single displacement reaction, a reactive element displaces another less reactive element in a compound. After checking the activity series for metals, I know that magnesium is more reactive than copper sulfate; so that in the reaction, magnesium takes place of the copper element in copper sulfate to produce copper metal and magnesium sulfate. During the reaction, a…

Both the sulfate and chloride reactions formed a white precipitate when the compound was added to 6 M HNO_3 and AgNO_3 for the chloride test and 6 M HCl and BaCl_2 for the sulfate test. There were no indications of the other anions in our compound. A brown ring did not form for the presence of nitrate, there was no indication of fizzing for the…

equivalent of spacer was coupled using 2.4 equivalents of inhibitor, 0.18 equivalents of copper sulfate, 0.36 equivalents of (+)-sodium-L-ascorbate, in a mixture of 10% H2O in DMF, 24 mL/mmol spacer. The mixture was placed in the microwave for 30 minutes at 80oC Pro6 Spacer (10) (30 mg, 0.036 mmol) and 18 (36 mg, 0.087 mmol) were dissolved in 778 µL DMF. Copper sulfate (1.62 mg, 0.006 mmol) and sodium-L- ascorbate (2.57 mg, 0.013 mmol) were dissolved in 86 µL H2O. The two solutions were combined…

Cyclohexanol requires going through an acid-catalyzed elimination of water for the synthesis of cyclohexane from cyclohexanol. To get cyclohexane from cyclohexanol you must remove the cycloalkane with fractional distillation, drying with anhydrous sodium sulfate, and analyzed by GC data and the bromine test. The reaction we are trying to accomplish going from cyclohexanol to cyclohexene is a secondary alcohol going through an E1 reaction. This is the unimolecular elimination reaction in…

Like the sodium phosphate buffer, the solid was dissolved in 300 milliliters of distilled in a 500-mL beaker using a stirrer and a magnetic stirring bar. The pH of the solution was then checked using the pH meter and it was brought down to the desired pH of 4.8 using…

9-fluorenol, which is the decrease of a molecule’s hydrogen content.6 The following chemicals were used in the experiment: 9-fluorenol, sodium hypochlorite (the oxidizing agent), sodium thiosulfate (the reducing agent), sodium bicarbonate, acetic acid, and acetone.3,6 To begin the experiment 9-fluorenol, acetone, acetic acid, and sodium hypochlorite were added in sulfate is added to remove excess water from the hexane layer that is collected using the separatory funnel.6 To determine the success…

“Classifying Chemical Reactions - Lab Report” I - Introduction - Chemistry is the study of the composition, structure, properties and change of matter. In chemistry, chemical and physical changes are used to help scientists understand how different substances react given various circumstances. A chemical change is any change resulting in the formation of a new chemical substance(s). A physical property is any change that does not involve the chemical makeup of a substance at all. In total…

ingredients that are not good for you. Preservatives Let's start with some of the obvious ones. Preservatives are ingredients used to prolong the shelf life of the product. Yet, they are often harmful to human health. Ammonium sulfate is one example. Yes, ammonium sulfate is a close relative to the ammonia that you use to clean the house. Its cleaning/sterilizing properties make it…

Sodium hydroxide was mixed with all cations, zinc, copper (II), cobalt (II), and potassium. Potassium, because it is a Group I metal, was not able to react with the sodium hydroxide to form a precipitate. The other three cations, copper (II), cobalt (II) and zinc, formed a precipitate with the initial reaction. When excess base (NaOH)…
