* Physical Science Unit 6: Acids, Bases, Solutions TEST
PSc.2.1.2 - Students will be able to explain the phases of matter and the physical changes that matter undergoes in order to: 1)Recognize that the formation of solutions is a physical change forming a homogeneous mixture. (Review from 8th grade.). 2) Develop a conceptual model for the solution process with a cause and effect relationship involving forces of attraction between solute and solvent particles. A material is insoluble due to a lack of attraction between particles. 3) Interpret solubility curves to determine the amount of solute that can dissolve in a given amount of solvent (typically water) at a given temperature. 4) Qualitatively explain concentration of solutions as saturated, unsaturated or supersaturated; dilute or concentrated.
PSc.2.2.6 - Students will be able to summarize the characteristics and interactions of acids and bases in order to: 1)Recognize common inorganic acids including hydrochloric (muriatic) acid, sulfuric acid, acetic acid, nitric acid and citric acid. 2) Recognize common bases including sodium bicarbonate, and hydroxides of sodium, potassium, calcium, magnesium, barium and ammonium. 3) Define acids and bases according to the Arrhenius theory. 4) Develop an understanding of the pH scale and the classification of substances therein. 5) Generalize common characteristics of acids and bases– pH range, reactivity with metals and carbonates (acids) or fats/oils (bases), conductivity.
Relate general household uses of acids and bases with their characteristic properties. 6) Explain what happens in a neutralization reaction, identifying each component substance.
