Science Enhanced Scope and Sequence Chemistry Virginia Department of Education 2012 1 Moles Lab Activities Strand Molar Relationships Topic Investigating stoichiometry Primary SOL The student will investigate and understand that chemical quantities are based on molar relationships. Key concepts include a) Avogadro s principle and molar volume; b) stoichiometric relationships; c) solution concentrations; d) acid/base theory; strong electrolytes, weak electrolytes, and nonelectrolytes; dissociation and ionization; pH and pOH; and the titration process. Related SOL The student will investigate and understand that experiments in which variables are measured, analyzed, and evaluated produce observations and verifiable data. Key concepts include a) designated laboratory techniques; b) safe use of chemicals and equipment; c) proper response to emergency situations; g) mathematical manipulations including SI units, scientific notation, linear equations, graphing, ratio and proportion, significant digits, and dimensional analysis.
