Oct 25,  · Abstract The Water of Hydration lab wishes to accomplish several objectives and conquer various skills in chemistry. Some of these objectives include determining the percent of eater in a hydrated salt, as well as determining the number of water molecules in each salt formula. In doing so, various apparatuses including a crucible and cover, a Bunsen burner, hydrated salt, and other items 50%(4).


CHEM - Expt 4 - Water of Hydration


Objective - Determine the percent of water in a hydrate. Salts are compounds composed of a metal ion plus a non metal or polyatomic ion, e. Hydrated salts or Hydrates are salts which have a definite amount of water chemically combined. Some common hydrates are:. The dot indicates an attractive force between the polar water molecules and the positively charged metal ion. On heating, the attractive forces are overcome and the water molecules are released leaving behind the anhydrous salt.

The water released on heating is called the water of hydration. Since heat is absorbed during this process, the reaction is "endothermic". In an "exothermic" reaction heat is liberated. Therefore, avoid letting the flame of the Bunsen burner rest on one spot of the crucible.

Heat gently by holding the bunsen burner in a sweeping motion. When decomposes a black solid, CuS, is formed. Canada V5G 3H2. Procedures Part A Part B.

Expermient 42 – Water of Hydration Goal: This is a survey lab where we will observe properties of hydrates through a series of experiments and we will determine the formula of a hydrate. Formula of a hydrate: AB·xH 2O where x is typically, but not always, a whole number. e.g., CaCl 2·2H 2O, Na 2SO 4·10H 2O Consider the meaning of the. Title: Water of Hydration Purpose: The purpose of this lab was to determine that all the water has been driven from a hydrate by heating a sample. Also another purpose was to use experimental data to calculate the moles of water released by a hydrate and to calculate the mass of %(17). In this lab we will take a hydrated compound and accurately determine the initial mass. We will then heat the hydrated compound to remove the water. We will then accurately determine the weight of the anhydrous barium chloride. Assuming the loss in mass is the mass of the water of hydration, the mole ratio of water to barium chloride can be.
