Ksp: review (grade 11)1) What is the molar mass of H2O?2) How many moles are in 18 g of NaCl?3) How many g of CaCl2are found in 2 L of a 3 M solution of CaCl2? (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 K2SO4?Hint: Add together the # mol K+from each source to get total # mol K+. Divide this by total number of L.Ksp (solubility product) - backgroundBottom 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 ignoredWe 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, KbEach subscript immediately indicates some detail about the equilibriumKw: equilibrium of water, Ka: acid, Kb: baseKsp: equilibrium between solid and ionsKsp - backgroundThe equilibrium between solids and ions is
