EFFECT OF CHANGES IN TEMPERATURE AND SDS CONCENTRATION ON THE STRUCTURE OF BEETROOT CELL MEMBRANES. Introduction Cellular Membranes or cell membranes are biological membranes that separate the interior of a cell from the outside environment. Cell membranes are selectively permeable to ions and some molecules and control the movement of substances in and out of the cell. (Danyk‚ 2013/14) Cell membranes separate and organize chemicals and reactions within cells by allowing selective passage

Question 1 1.1 Silica gel chromatography: This is known as the stationary phase in column chromatography. Firstly‚ the tapered exit of the column is sealed using porous material. This porous material serves as support for the packing material‚ and prevents it from exiting the pipe. Thereafter‚ silica gel is compacted into the glass pipe to make the separating column. In finishing preparation of the column‚ the solvent which is used as the mobile phase is then passed through the dry column. Then the

PRACTICAL 2: Preparation of sodium hexanitrocobaltate (III) Date: 12 March 2014 INTRODUCTION Sodium hexanitrocobaltate (III) is a coordination complex which has the formula Na3[Co(NO2)6]. This compound is yellow in colour. It consists of a central Co3+ ion surrounded by six nitro ligands [1]. This compound is used as a qualitative test for potassium and ammonium ions (so long as certain other cations are not present) [1]. Potassium and ammonium are insoluble in water‚ while sodium is [1]. Hence‚ the

that are in the hydrate. Copper(II) sulfate pentahydrate‚ or CuSO4 * 5H2O‚ is a ratio of one copper sulfate to five (penta) molecules of water. Copper sulfate pentahydrate is a blue hydrate while anhydrous copper sulfate (CuSO4) is white. To get anhydrous copper sulfate‚ copper sulfate pentahydrate must go through an endothermic reaction and have all of its water molecules evaporated. It then becomes the white‚ flaky‚ and chalky material anhydrous copper sulfate. Adding
