Almost anything such as fluids that dissolves can break the binding of the molecules. In addition adsorption

The effect of alcohol concentration on the cell membrane Abstract: In this experiment I found out that as the concentration of the alcohol was increased so did the colour intensity of the solution. This is because the higher concentration of ethanol‚ results in more damage done to the cell membrane‚ resulting in leakage of red pigment from the cell. If the membrane is damaged more‚ more red pigment will leak out of the membrane and into the ethanol. Hypothesis: The higher the concentration

In most cases‚ such natural products get their properties from a mixture of organic compounds. In this experiment you will prepare two esters of o-hydroxybenzoic acid‚ more commonly known as salicylic acid. One of the esters‚ acetylsalicylic acid‚ is aspirin‚ the common analgesic. We will synthesize aspirin by mixing salicylic acid with acetic anhydride. The

Twenty years ago‚ super-maximum-security prisons were rare in America. As of 1996‚ over two-thirds of states had "supermax" facilities that collectively housed more than 20‚000 inmates. Based on the present study‚ however‚ as of 2004‚ 44 states had supermax prisons. Designed to hold the most violent and disruptive inmates in single-cell confinement for 23 hours per day‚ often for an indefinite period of time‚ these facilities have been lightning rods for controversy.
