Charbonneau Grand Valley State University The point of this experiment was to observe if the different concentrations of sucrose would change the speed of osmosis. Osmosis is a process of a fluid that will pass through a semipermeable membrane into a solution which most of the time has a higher concentration. Osmosis will be demonstrated throughout the lab. The importance of osmosis in a plant and animal cell there is a cell membrane‚ which helps liquids and some dissolved solids go in and out of it.

compound. Introduction The solubility product constant‚ Ksp‚ is a particular type of equilibrium constant. The equilibrium is formed when an ionic solid dissolves in water to form a saturated solution. The equilibrium exists between the aqueous ions and the undissolved solid. A saturated solution contains the maximum concentration of ions of the substance that can dissolve at the solution’s temperature. The equilibrium equation showing the ionic solid lead chloride dissolving in water is:

Comparison – Contrast Essay in Meyer’s The Seven-Per-Cent Solution Father of detective work‚ Sherlock Holmes and father of psychoanalysis‚ Sigmund Freud‚ can be compared and contrasted in Nicholas Meyer’s The Seven-Per-Cent Solution. Sherlock Holmes can be identified as one of the most brilliant fictional characters of the 19th century period. As a “consulting detective”‚ he uses his extraordinary abilities and logical reasoning to solve some of the most difficult cases. Equally as brilliant

Housing Bubbles in Metropolises in China Introduction The boom of house market has emerged accompanying with the soaring development of Chinese economy over the last two decades. Although the prosperity of real estate sector makes contributions to the growth of national fiscal revenue and Gross Domestic Product‚ it also raises a serious problem --- housing bubbles‚ defined as the housing prices deviate too much from its fundamental value (Flood and Hodrick‚ 1900)‚ especially in metropolitan

Introduction: The importance of this lab is to get a deeper understanding of how the concepts of solutions and insolubility applies to the lab’s purpose of making chalk using precipitation reactions. A precipitation reaction is when a solid/ precipitate (insoluble) is formed when two solutions that contain soluble salts are combined. Some additional scientific concepts investigated in this lab are insolubility‚ double replacement‚ and limiting reactants. Insolubility occurs when a solute is incapable

In the Shells lab‚ we were to test the effect of pH on shell strength. The independent variable in this experiment is the type of liquid that we put the shell in and the independent variable is the shells’ strength. The first thing we did was get our materials and label the two shells. The shell that was going into the vinegar was labeled “E” (which stands for experimental) and the shell that was going to be put in the salt water was labeled “C” (which stands for control since it is the control of
