Obtain a clean crucible. Weigh the crucible with the hydrated magnesium sulfate. Record the weight in your data table. Hey Janice, you still need to write two other improvements for the lab.
One simply needs to determine the number of moles of water per mole of anhydrous compound in the hydrate: Occasionally more than one solvent is found in a crystal, and often the stoichiometry is variable, reflected in the crystallographic concept of "partial occupancy.
Discuss at least three feasible improvements and why with reference to the other discussion questions and errors. Weigh the crucible with the hydrated magnesium sulfate. When they are at approximately room temperature, weigh the crucible and contents and record the mass in your data table.
Clean up all materials Observation s: Record all weighings accurate to the nearest 0. What follows is an example of each way. Finally, we would try the experiment few more times in order to get the best possible result.
Given the mass of a sample of the hydrate with water bound in the crystal and the mass of anhydrous salt without water bound in the crystal of known formula obtained on heating, it is easy to find the formula of the hydrate. Measure the mass of the evaporating dish to the nearest 0. Clara barton childhood events essay Clara barton childhood events essay my favourite recipe essay at6 harvard video essay importance of literature review in academic research paper.
There are three different ways you can approach this type of problem. Suggest a source of error not already mentioned that would result in a value of x that is a. To find the formula of a hydrate. Solution using percent anhydrate: How would that change your ratio.
The actual ratio is 1. Junsung and Janice If the compound had not been fully dehydrated, then the mass of the leftover H2O would be counted as the mass of the solid. Remove the cup a second time 9. How would your ratio change if you did not dehydrate the compound fully.
Water is noteworthy because it is reactive, whereas other solvents such as benzene are considered to be chemically innocuous. Hydrate Lab. Purpose: The purpose of this lab is to determine the relationship between the amount of hydrate in a copper sulfate compound.
Background: Hydrate - A compound that contains the water molecule. Crush the copper sulfate hydrate crystals into a fine powder using the mortar and pestel.
2. Measure the crucible empty then place in. Chemistry Lab Report Water Hydration Introduction: A hydrated crystal or hydrated occurs when water becomes tightly attracted to a metal salt base on it’s polarity.
The water molecules maintain integrity as molecules, however they are considered to be part of the formula of the hydrate. CHEMISTRY LAB: HYDRATED CRYSTALS WHAT TO TURN IN: Hypothesis Data Table Calculations (5) Questions (4) OBJECTIVES To review and observe the characteristics of a hydrate To fine the experimental and theoretical percentages of water in the hydrate.
In chemistry, a hydrate is a substance that contains water or its constituent elements. The chemical state of the water varies widely between different classes of hydrates, some of which were so labeled before their chemical structure was understood.
