Use data from Figure 9-9 to predict the type of cubic unit cell adopted by (a) BaO; (b) CuI; (c) (The radii of and S2 ions are 135 and 198 pm, respectively.)
CHEM Week 8 Notes • Solution – is a homogeneous mixture of 2 or more substances o Type solute = solution • Solutions have different electrolytic properties o If the conductivity = no light; then there is no dissociation of ions o If the conductivity = dim light; then there is a partial dissociation of ions o If the conductivity = bright light; then there is a complete dissociation of ions • Strong/Weak acids/bases o Strong acids/bases = complete dissociation of ions or no dissociation of ions o Weak acids/ bases = partial dissociation of ions • Types of reactions o Precipitation reaction – soluble ionic (aq) reactants yield an insoluble solid product called a precipitate o Acid-base neutralization reaction – an a
