Lab 6: Water of Hydration Name: Smrithi Prem Date: March 9 th 2005 Partner: Michael? Lab Section : 9-5 class sect: 9-4 Objective: The objective of this lab is to determine the number of moles of water in the hydrated compound. Material and Equipment : 1. Two beakers 2. Scale 3. Hot plate 4. Desiccator 5. Magnesium sulfate.nH 2 O 6. Nickel Sulfate. nH 2 O Procedure: First, weigh the beaker and then take about 1.0-1.5 grams of the compound in the beaker. Place the beaker with the compound on the scale and record the weight. Then place the beaker with the compound on the hot plate and heat for about 10 minutes or until water is thoroughly removed. Take the beaker and place it in the desiccator to allow it to cool. Once the sample is cooled, take the weight and record it. Repeat the same procedure for the second sample. Data and Observation Data: 1. Mass of beaker = 51.59 g 2. Mass of beaker + MgSO 4 .nH 2 O = 52.70 g 3. Mass of MgSO 4 + beaker = 52.15 g 4. Mass of MgSO 4 .nH 2 O = 1.11 g 5. Mass of MgSO
