Ksp: review (grade 11) 1) What is the molar mass of H 2 O? 2) How many moles are in 18 g of NaCl? 3) How many g of CaCl 2 are found in 2 L of a 3 M solution of CaCl 2 ? (see pg. 130 if you need help) 4) What is the concentration (in mol/L) of K + when 2 L of 1.5 M KCl is mixed with 1 L of 3 M K 2 SO 4 ? Hint: Add together the # mol K + from each source to get total # mol K + . Divide this by total number of L. Ksp (solubility product) - background Bottom line: 1) Ksp is similar to Kc, 2) It deals with ions instead of gases, 3) one side of the chem. equation has a solid, which is ignored We have used Kc in equilibrium problems “K” indicates an equilibrium “c” indicates units are mol/L (in this course it will also indicate we are dealing with gases) There are other types of K: Ksp, Kw, Ka, Kb Each subscript immediately indicates some detail about the equilibrium Kw: equilibrium of water, Ka: acid, Kb: base Ksp: equilibrium between solid and ions Ksp - background The equilibrium between solids and ions is
