Percent Water in a Hydrate PURPOSE To determine the percent water in a hydrate sample. INTRODUCTION Many substances contain water molecules as a part of their crystal structure. We call such solids hydrates‚ and we call the bound water the water of hydration. A hydrate has a definite number of water molecules bound to each anhydrous salt unit. The formula of the hydrate copper(II) sulfate pentahydrate is CuSO4 · 5 H2O The dot indicates that the molecules of water are attached to the ions in

Epithelial tissue always rests on a basement membrane. The characteristics are: lack of visible interstitial space‚ many cells‚ and no blood vessels. A. Simple Squamous: (kidney slide). Look in the outer edge or cortex of the kidney to find a Bowman’s capsule. The lining of the Bowman’s

Abstract: Water potential is the measure of free energy of water in a solution. The purpose of this lab was to find the water potential of a potato cell. The problem of this lab was‚ if there was a high molarity of solute‚ would it have a positive or negative water potential? The hypothesis of the experiment was‚ if there is a high molarity of solute then the water potential would be lower or negative. After obtaining potatoes‚ we cut them into pieces‚ weighed them‚ and then placed them in a solution

Tim Readmond AP Biology Lab Report I. Title a. Modeling Diffusion and Osmosis II. Introduction a. If one places a 1.0 M solution of glucose inside a bag and then places that bag into a beaker containing a 1.0 M solution of sucrose‚ the percent of mass lost in the bag is 10.5%. The solution in the bag is hypertonic while the solution in the beaker is hypertonic‚ which is why water moves from the bag to the beaker and the bag loses mass. b. The purpose of this experiment is to see whether
