Solution A homogeneous mixture of two or more substances with each substance retaining its own chemical identity. Solute – substance being dissolved. Solvent – liquid water. General Properties of a Solution 1. Contains 2 or more components. 2. Has variable composition. 3. Properties change as the ratio of solute to solvent is changed. 4. Dissolved solutes are present as individual particles. 5. Solutes remain uniformly distributed and will not settle out with time. 6. Solute

Title: Preparation of Solutions and Buffers Objectives: 1. To learn and understand the theory‚ principle and formula behind buffers and solutions preparation. 2. To learn the methods for buffers and solutions preparation. Introduction: (Wikipedia‚ 2013) Solute is a substance dissolved in another substance. Solvent is a substance in which the solute is dissolved by it. Solution is a mixture of two or more substances. The amount of solute dissolved in a solvent is called concentration

Abstract This laboratory involved utilizing equipment to dilute a sugar water solution. It also created solutions containing varying levels of concentrations and densities. Equations were used to figure the molecular weight of the sugar‚ and the number of moles of sugar in the volumetric flask. There was also an equation to figure the Molarity‚ as well. As a result of the experiment‚ I now have a better understanding of the density of a concentration‚ and what Molarity is . Observations Data

1. Solution is a homogeneous mixture composed of only one phase. In such a mixture‚ a solute is a substance dissolved in another substance‚ known as a solvent. Suspension is a heterogeneous mixture in which the particles are large enough to be seen by a microscope or the unaided eye and eventually‚ they settle out of the mixture. A colloid is a substance microscopically dispersed throughout another substance. Unlike colloids‚ suspensions will eventually settle. The suspended particles are visible

Lab Background information: A hypertonic solution is a concentration that is higher than the solution. A Hypotonic solution is a concentration that is lower than the solution. An isotonic solution is a concentration and solution that is the same amount. Hypothesis question: What will happen if you put a potato in hypertonic solution? What will happen if you put a potato in hypotonic solution? What will happen if you put a potato in isotonic solution? Hypothesis statement: If you put sugar

Is punishment always the right solutions to stop crime? Determine “right” – practical and moral reasons. Effectiveness and whether it is right in terms of morality. Introduction: Punishments are meted out for three reasons – deterrence‚ retributivism‚ and incapacitation. The first‚ deterrence seeks to prevent future wrong doing. Retributivism is linked to notions of justice where crime must be met with an appropriate punishment. The last‚ incapacitation‚ seeks to protect society at large from

Determining the Concentration of a Solution: Beer’s Law Purpose: The purpose of the experiment is to determine the concentration and formula of an unknown cobalt nitrate solution by measuring absorbance. Introduction: A Colorimeter will be used to determine the concentration and formula of an unknown cobalt nitrate solution. The colorimeter sends blue light from the LED light source to pass through the solution and hit a photocell. A solution with a higher concentration will absorb more
