(a) Following the example of Mg(OH)2 in Section 7-5, write the equations needed to find the solubility of Ca(OH)2. Include activity coefficients where appropriate. Equilibrium constants are in Appendixes F and I. (b) Neglecting activity coefficients, compute the concentrations of all species and compute the solubility of Ca(OH)2 in g/L.
CH 101 Lecture 1 January 13, 2017 Scientific Method Scientists use the scientific method to find explanations for the world around them Steps: o Observation o Hypothesis o Experiment o Theory Repeat process until theory becomes a law Matter All matter consists of atoms and molecules. Atoms combine to form molecules. Molecules may have the same type of atoms or different types of atoms. The ancient Greeks were the first to come up with the theory that matter consists of indivisible constituents. Atomic Structure Atoms are known as “the building blocks of matter” Scientists realized that the atom consisted of charged or uncharged (neutral) entities. The atom consi
