Solutions: • Use the terms solute and solvent in describing a solution • Sketch a solution at the particle level (ionic and molecular) • Design and conduct an experiment to determine the factors affecting the rate of dissolution (agitation, particle size/surface area, temperature) • Describe concentration qualitatively and quantitatively (relative amount of solute and molarity calculations) • Define and relate parts per million (PPM) to any environmental issue Colligative Properties: • Measure change in boiling and/or freezing point of a solvent when a solute is added • Apply colligative properties (road salt, cold packs, antifreeze, etc.) Acids & Bases: • Calculate molarity of acids and bases • Relate hydrogen ion concentration to pH values and to the terms acidic, basic or neutral. [1*10^-7= pH 7], [1*10^-3= pH 3] • Using an indicator, measure the pH of common household solutions and standard laboratory solutions, and identify them as acids and bases • Determine the concentration of an acid or a base using a simple acid-base titration. (Moles of H+ = Moles of OH- ) • Relate acids and bases to real world problems/issues. • • •

Calculate Molarity

RST-6: Analyze the author’s purpose in providing an explanation, describing a procedure, or an experiment in a text, defining the qu estion the author seeks to address. RST-7: Translate quantitative or technical information expressed in words in a text into visual form (e.g., a table or chart) and translate information expressed visually or mathematically (e.g., in an equation) into words. RST-10: By the end of grade 10, read and comprehend science/technical texts in the grades 9-10 text complexity band independently and proficiently. WHST-5: Analyze the structure of the relationships among concepts in a text, including relationships among key terms (e.g., force, friction, reaction force, energy ). WHST-6: Use technology, including the Internet, to produce, publish, and update individual or shared writing products, taking advantage of technology's capacity to link to other information and to display information flexibly and dynamically.
