When calcium nitrate, Ca(NO32, dissolves in water, it dissociates into its ions. We can represent that process by the following equation Ca(NO3)h(s) Ca2(aq) 2NOs(aq) When 1.5 mol calcium nitrate dissolves in water, how many moles of ions should be present in solution? O 9.0 moles of ions O 1.5 moles of ions O 30 moles of ions O 13.5 moles of ions O 45 moles of ions

What is the total concentration of all ions (the sum of their individual concentrations) in aqueous solutions of the following? Hint: Each substance is an electrolyte that dissociates in water to produce ions. Use the link table of polyatomic ions if you do not recognize the polyatomic ion. For example, Na2SO4->2Na1++ SO,2- when it dissolves, so a 1 M soln of Na,SO4 is 2M in Na1 and 1M in so2- and the total concentration of ions is 2 M 1...

(4 pts) The 0.040 M solution of CoCl2 used in Experiment 7 is prepared in the prep lab from solid CoCl2:6H2O. When CoCl2:6H2O dissolves in water, it dissociates to form two ions, one of which is a complex (the species responsible for the solution's color). In the boxes below, give the molecular formulas of the two ions present in a solution of cobalt(II) chloride, and the predicted color of the solution. Cation: Anion: Color:
