C2.4 use an inquiry process to investigate the law of conservation of mass in a chemical reaction (e.g., compare the values before and after the reaction), and account for any discrepancies [PR, AI]
C2.5 use an inquiry process to investigate acid– base neutralization reactions (e.g., neutralize a dilute solution of sodium hydroxide with dilute hydrochloric acid and extract the sodium chlor- ide produced) [PR, AI]
C2.6 conduct an inquiry to classify some common substances as acidic, basic, or neutral (e.g., use acid–base indicators or pH strips to classify com- mon household substances) [PR, AI]
C2.7 investigate applications of acid–base reac- tions in common products and processes (e.g., compare the effectiveness of different brands of antacid tablets, using quantitative analysis) [PR, AI]
C3. Understanding Basic Concepts
By the end of this course, students will:
C3.1 describe the relationships between chemical formulae, composition, and names of simple compounds (e.g., carbon dioxide, CO2, has one more oxygen atom than carbon monoxide, CO)
C3.2 name and write the formulae for simple ionic and molecular compounds (e.g., NaCl, NaOH, H2O, CO2)
C3.3 write word equations and balanced chem- ical equations for simple chemical reactions (e.g., 2H2 + O2 ➞ 2H2O)
C3.4 describe the process of neutralization for simple acid–base reactions (i.e., an acid reacts with a base to form a salt and often water)
C3.5 describe how the pH scale is used to identify the concentration of acids and bases
