Concentrations of Solutions (Section)

In each of the following pairs, indicate which has the higher concentration of I- ion:

(a) 0.10 MBaI2 or 0.25 M KI solution,

(b) 100 mL of 0.10 M KI solution or 200 mL of 0.040 M ZnI2solution,

(c) 3.2 M HI solution or a solution made by dissolving 145 g of NaI in water to make 150 mL of solution.

CHEM 112 Notes (1-13-16) Clicker Question: Calculate the molarity of a 12.0% sulfuric acid solution (2 SO4; 98.08 g/mol) having a density of 1.080 g/mL. = 12% H S2 4 MM=98.08 g/mol d=1.080 g/mol 12g H 2O (4er 100g of solution) 12 24 98.08 /= 0.122 24 100 ×1 1.080 = 92.59 = 0.09259 0.122 24= 1.32 0.09259 Remember: Theory guides, but experiment decides -Chemistry is an experimental science. Actually doing the experiment will yield more accurate solutions than theory Principles of Solubility:  Dynamic—able to change it o Temperature can change the dynamic process  Why this happens: o Enthalpy (ΔH):  Heat given off or absorbed (endothermic/exothermic)  Usually a spontaneous reaction is exothermic and gives off heat, but some spontaneous solutions are endothermic  Types of Interactions: o Solvent-solvent o Solute-solute o Solute-solvent  The Solution Process: o First need to u
