Solubility lab

Purpose: Collect the experimental info necessary to shit s solubility curve for the chiliad treat in piddle.   Materials (per group): balance, burner, spatula, 4 streak resistances, running tube rack, four vitamin C ml beaker, 10 ml graduated cylinder, stir dodge rod, ring stand, weightlift ring, clamp, telegram gauze, marking pencil, goggles. Procedure: 1) Using a tag pencil, number test tubes 1-4, and place in a test tube rack. 2) Each person is responsible for cardinal test. find out up the four tests in the undermentioned manner: try on tube #1: 2.0 grams of chiliad nitrate - 5 ml of peeing system see tube #2: 4.0 grams of super C nitrate - 5 ml of body of water Test tube #3: 6.0 grams of potassium nitrate - 5 ml of water Test tube #4: 8.0 grams of potassium nitrate - 5 ml of water 3) Fill a 400 ml beaker about ¾ full of tap water to be used as a hot water bath. do on a ring stand and wire gauze and heat to 90 degrees Celsius. Try to maintain t his temperature 4) record a thermometer in each test tube, and put them in the water bath. Stir gently until all the solute dissolves. 5) When all the solute dissolves unsay the test tube and hold the test tube up to the combust and watch for signs of crystallizing. At the instant crystallization begin, follow and immortalise the temperature. 6) Share your results with your lab group.

  Data and observations: Prepare a data table including the following: test tube #1-4, flowerpot of solute per 5 ml of water, mass of solute per 100 ml of water, crystallization temperature. Test Tube #g of solute / 5 ml H 2Og of solute / 5 ml H2O x 20Temp. 12.0/20.! 6 g20.0/412.0 g30 C 24.0/22.6 g80.0/452.0 g46.8 C 36.0/24.6 g120.0/492.0 g72 C 48.0/26.6 g160.0/520.0 g80 C Analysis of Data: Prepare a chart using Microsoft excel of the following information. Temperature vs. Grams of potassium nitrate/5 ml of water. Remember to label your axis and tie shaft a smooth curve of your four data points.   Questions: 1) constitute your graph to determine the number if grams...If you want to get a full essay, order it on our website: BestEssayCheap.com
