B2.4 conduct qualitative analyses of an unknown sample (e.g., a household or workplace chem- ical), using a flow chart and experimental procedures, including flame tests and precipita- tion reactions, to determine the presence of metal ions [PR, AI]
B2.5 identify an unknown gas sample (e.g., hydrogen, helium, neon) by observing its emis- sion spectrum and comparing it to the spectra of known gases [PR, AI]
B2.6 use a table of solubility rules to predict if a precipitate will form in a given chemical reaction, and identify the precipitate formed [AI]
B. Understanding Basic Concepts
By the end of this course, students will:
B3.1 explain the relationship between the atomic number and the mass number of an element, and the difference between isotopes and radio- isotopes of an element
B3.2 describe various types of chemical reactions, including synthesis, decomposition, single dis- placement, and double displacement reactions
B3.3 explain basic procedures used in qualitative analysis of elements and compounds, including flame tests, precipitation reactions, and the ob- servation of emission spectra
B3.4 relate observations from investigations using flame tests and emission spectra to the concept of quanta of energy proposed by Neils Bohr
