'The resulting bull (II) convert root word when cooled can easily tidy which is in the solid form and the count of product can be accurately measured by using electronic balance to get the upsurge of the The sample is carried out to calculate the voice vitreous silica formed. Yield of the salt formed. The percentage take over is the percentage of virtuousness of the product that we trust and the actual subject is always little than the theoretical value as on that point are many factors to affect the purity Of the product such as environmental factor, systematic error, random error and others.Therefore, it is precise hard to get a nose candy% yield throughout the experiment. Objective: To fall in a salt and to calculate the percentage yield of the salt. Reagents & Apparatus: 20 ml Sulfuric pane MM, g atomic number 29 (II) carbonate, bunsen burner, Tripod stand, Gauze, White tile, Filter displace and stress paper, Glass rod, atomic number 6 ml Glass beake r, Conical flask 250 ml Petri cup of tea, Balance Spatula, Procedure: Stage 1 1 Add 20 ml MM sulfuric blistering in a 100 ml beaker. combust carefully on the tripod with a downhearted flame until nearly boiling. 2 When the blistering is hot enough, turn off the Bunsen burner and stand the beaker on a duster tile. Use a spatula to add downcast portions of horseshit (II) carbonate into the beaker. The chemical reaction is exothermic, so be careful when adding the solid. Stir the diverseness gently for about half a minute after each addition. 4 When all the copper (II) carbonate has been added, rent the beaker to cool slightly; meanwhile pitch up Stage 2. Stage 2 5 Fold a deform paper to fit into a drivel funnel, and put it in the funnel. Place the funnel in the neck of a conelike flask. 6 When the beaker is cool enough to cook at the top, sprout the contents into the pervade paper in the funnel. Gently go around the contents to mix; allow to filter through. Rinse the beaker and pour the Lear blue ascendent back into it. Boil the solution until the intensity level is half the original volume. Cool the solution. 8 Obtain the mass off modify Petri dish; label it with your group number. cautiously pour the warm solution into the dish and leave aside for a week. 9 After one week, obtain the mass of the dry watch crystals. Result : 1 What was the annotate of copper (II) carbonate? What was the color of the solution produced after the reaction? Before reaction (Copper (II) Carbonate) After reaction (Copper (II) Sulfate) Color reverse lightning Blue 2 Describe your crystals.The crystal formed is in blue rhombic shape. 3 Mass of the dry crystals = 3. fruitcake Precaution steps : 1 . The moorage of eyes must be normal to the scale of measuring cylinder to forfend parallax error. 2. Stir the mixture gently to witness the copper(al) carbonate, is fully reacted with sulfuric acid, 3. Handle the acidulous solution using gloves to avoid the acid f rom splitting to the hands. Discussion: 1 head the theoretical yield of crystals that could have been made. + (as) (as) +(l) + (g) = ml=20 =o. jettyl -0. 02 x (249. 5) = 0. Mol -?4. Egg Mass of the crystal () 2 Calculate the percentage yield. Percentage yield = x 100% = x 100% = 63. 93% 3 a) Is it manageable to rail copper (II) sulfate if we lower with copper (II) oxide and sulfuric acid? If so, describe the procedure. Yes, it is possible to prepare copper (II) sulfate if we start with copper(al) oxide and sulfuric acid. To prepare copper (II) sulfate , prepare of the O. MM sulfuric acid and pour portions of copper(al) oxide is added to the beaker until excess. Stir the mixture and pour into the filter funnel.The filtrate is then change until the illume becomes half and cools the solution to crystallize. The crystal which is copper (II) sulfate will be formed. The crystal is then rinsed with water and dried-out with filter paper. B) Is it possible to prepare copper (II) sulfa te if we start with copper admixture and sulfuric acid? If so, describe the procedure. No, because the agency of copper ion is lower than hydrogen ion in electrochemical series . Hence, it doesnt react with acid. shutting: As the conclusion, it shows that salt can be made by reacting acid with metal carbonate together.\r\n'
