Mixtures and Solutions can often become confusing because solutions are mixtures‚ but not all mixtures are solutions. A mixture can either be homogeneous or heterogeneous. A homogeneous mixture is where the mixture’s components are distributed uniformly within the mixture. A heterogeneous mixture is where the components are not uniform. Mixtures can either be miscible or immiscible‚ the difference being whether or not the mixture forms a homogeneous mixture or not. In a solution a solute is soluble

This assignment must be submitted no later than November 22nd‚ 2011. 1. What is a true solution? Explain why the solute does not settle out of a solution. Is it possible to have one solid dissolved in another? Explain. In metals it would be called an alloy. 2. An aqueous solution of KCl is colorless‚ KMnO4 is purple‚ and K2Cr2O7 is orange. What color would you expect of an aqueous solution of Na2Cr2O7? Explain. Orange. 3. Explain why hexane will dissolve benzene but will not dissolve

constituents as cations and non-metallic constituents as anions. In this experiment‚ you will analyze a known solution that contains the entire Group I cations—silver‚ lead‚ and mercury (I)—and an unknown solution to determine which ions are present and which are absent. II. DISCUSSION: The chlorides of Pb2+‚ Hg22+ and Ag+ are all insoluble in cold water. They can be removed as a group from solution by the addition of HCl. The reactions that occur are simple precipitations and can be represented by

Cell Fractionation: Isolation of Mitochondria from Cauliflower and Determination of Specific Enzyme Kinetics Introduction Mitochondria is an organelle found in eukaryotic cells that play a role in biochemical processes such as respiration and energy production. Mitochondria even play an important role in apoptosis‚ or programmed cell death. This is achieved by disruption of electron transport‚ oxidative phosphorylation‚ and ATP production or even the release of proteins that trigger activation
