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…

Title: Separations of a Mixture Notes: - H¬2O, Copper Sulfate, Starch - H2O (water)- liquid, solvent, boiling point: 100 C, freezing point: 0 C. - Copper Sulfate- solid, soluble, forms an aqueous solution, is a salt. - Starch- solid, macromolecule (long chain sugar), not very soluble in water at low temperatures. - When H2O, Copper Sulfate, and starch are mixed together, it forms a heterogeneous mixture. - Aqueous solution of copper sulfate with a suspension of starch. Research Question: What…

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.…

show a nonspontaneous reaction. The Gibbs free energy, however, shows that the reaction is spontaneous at high temperatures when the decahydrate crystals melt. The reaction proceeds to become endergonic as the temperature decreases to in order to stabilize the anhydrous crystals. Reference List Abhat, A.

It can not be determined that ammonium sulfate can be used to find the LC50 of Daphnia Magna. In every trial, there was no data that was consistent or logical to be used to determine an accurate LC50. The LC50 is the point at which the concentration of a pollutant is lethal to 50% of the organisms. Static toxicity tests occur when the aquatic organisms are exposed to the same pollutant concentration for the duration of the test. The data in the first two trials had mostly 100% death rates…

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.…

dichloromethane in the two hundred and fifty (250) milliliter beaker is certain to contain small amounts of water from the coffee, even if you can’t actually see visible water droplets. Therefore, it must be “dried” to remove any water. If there are some visible droplets of water/coffee present, decant the dichloromethane into a new dry beaker, attempting to leave the water droplets behind when decanting. If no visible droplets of water are present, skip the decanting step. When there are no…
