NYSTCE Chemistry: Solutions & Solubility Chapter Objectives
Teacher candidates seeking certification in New York are required to successfully complete the NYSTCE Chemistry exam as part of the certification process. Criterion-referenced and objective-based, these tests measure content-area knowledge against a state-determined set of criteria. This chapter addresses the competencies in Subarea V: Stoichiometry and Solutions, which is weighted at 13% of the test.
The NYSTCE Chemistry exam is composed of six subareas that form the source of the 90 multiple-choice questions on the test, while Subarea VII contains the criteria for the one constructed-response assignment. For the latter, you will be given a topic in response to which you must compose an essay or article between 150 and 300 words in length. The test is computer-based.
1. The Rate of Dissolution: Factors and Definition
Learn what dissolution is and the factors that affect the rate of dissolution, such as temperature, surface area, polarity and pressure. Learn what miscible and immiscible mean in regards to liquids.
2. Solutions, Electrolytes and Nonelectrolytes
Learn what a solution is and how it is formed. Learn how to express the concentration of a solution in terms of molarity, molality and mass percent. Discover the differences between an electrolyte and a nonelectrolyte.
3. Solubility and Solubility Curves
Learn what solubility is as well as the definitions of 'saturated,' 'unsaturated' and 'supersaturated.' Learn how to determine the solubility of a substance in water by using a solubility curve. Discover the effects of pressure and temperature on the solubility of liquids, solids and gases.
4. Calculating Molarity and Molality Concentration
Learn the abbreviations and meaning of molarity and molality. Then apply what you have learned by going over some sample calculations with given concentrations.
5. Calculating Dilution of Solutions
Learn what a solution is and how to properly dilute a new solution from a stock solution. Learn the dilution equation that combines molarity, the volume of stock solution and desired solution to determine how much stock solution is needed for the new solution.
6. Colligative Properties and Raoult's Law
Learn how vapor pressure and osmotic pressure are colligative properties. Learn Raoult's Law and how to use it to determine the vapor pressure of a solution. Learn the equation for determining osmotic pressure and how to use it to determine the molar mass of a substance.
