    Copper (Ⅱ) Sulfate Using the Empirical Formula Introduction In this experiment, the molecular formula of hydrated Copper (Ⅱ) Sulfate will be determined. In order to determine the molecular formula, the empirical formula is needed which is the ratio of moles of one substance to another. In this experiment, it is the ratio of Copper (Ⅱ) Sulfate to water. CuSO₄・XH₂O The empirical formula can be determined if the moles of the compared substances are calculated and then divided by the smallest mole. Since there are large quantities of particles in any given substance, the mole is a unit used to group particles to make it easier to calculate large numbers. The amount of particles in one mole is…

    This is a test to see if SO4 is present in the solution. If the mixture has a white precipitate of Barium Sulfate, then the solution has a sulphate ion present (4). Taking one of the remaining test tubes, add 0.1 mL of BaCl2 into the solution and mix well. HCl Test Fig 5. If HCl is present in the solution, bubbling and a strong smell of ammonium should be present. Using the remaining test tube, add 0.1 ml of HCl into the solution. Record your findings. Record Conductivity using…

    the experiment was to determine weight % of sulfate inside an unknown sample compose of Na2SO4. The sample was dried, weighed and dissolved in water and hydrochloric acid. Barium chloride was then added in excess to drive the precipitation process to completion. Heat was use to digest the precipitate before it was filtered through an ashless filter paper and ignited to constant weight. From mass of the sample and mass of the precipitate, the percentage of sulfate in the unknown sample was…

    The different chemicals that were used in this experiment were Pilocarpine, Atropine Sulfate, Epinephrine, Digitals, Potassium, Sodium, and calcium ion concertation. Pilocarpine stimulates the effect of parasympathetic nerve stimulation by enhancing acetylcholine release. Atropine Sulfate is a drug that blocks the effect of the neurotransmitter acetylcholine which is liberated by the parasympathetic nerve endings. Cardiac muscle and skeletal muscle are both different in functionally and in fine…

    The study consisted of five treatment groups, these groups were divided out as follows. Glucosamine solo, chondroitin sulfate solo, a mixture of glucosamine and chondroitin sulfate, celecoxib which is an anti-inflammatory drug, and an inactive substance that looks like the study substance which in medical terms is known as a placebo. Glucosamine and chondroitin sulfate and the sequence of the two were correlated with the placebo to assess whether any of these control groups improved joint pain.…

    By: Jorden and Claudia In the next couple paragraphs you will learn about copper sulfates names, its agricultural uses, its industrial uses, the many hazards, safety precautions, activity series, and displacement reaction. Also copper sulfate can be very useful but it is also very dangerous. Copper sulfate (CuSO4 and 5H2O) is also known as Blue Vitriol, Bluestone, Salzburg vitriol, Roman vitriol, Turkish stone, and Blue copperas. The mineral form of CuSO4 is chalcanthite. The white-gray…

    to use the gravimetric method to determine the concentration of sulfate. Gravimetric analysis is a method used to determine the mass or concentration of a substance by measuring a change in mass. To determine the concentration of the sulfate, the precipitation of Barium sulfate is done first by adding the sulfate solution with hydrochloric acid, then heating while stirring it. Next is the washing and filtration of the Barium Sulfate precipitate, using a vacuum pump and a crucible. Lastly, is the…

    Reaction # Observations Equation 1 We mixed Aluminum Sulfate with Barium Nitrate in two test tubes. The Barium Nitrate is a clear liquid that had no smell. The Aluminum Sulfate also was a clear liquid with no scent. When mixed, the center of the liquid turned into a milky white precipitate. After 2 minutes the white substance sank to the bottom while the clear liquid sat on top. Al2(SO4)3(aq)+3Ba(NO3)2(aq)--> 2Al(NO3)3(aq)+3BaSO4 (s) 2 First we felt the material of a piece of Magnesium.…
