Help with 13
Solution B has greater solute (solute "solute particles") concentration than does solution A. Solution A is hypoosmotic to Solution B. 13. You are instructed to make one liter of 150 mM of NaCI. Given the salt (NaCl) and equipment needed for weighing and measuring volumes, tell exactly how you would make this solution. (show all calculations). What is the osmolarity of this solution?

Answer QUESTION 5
Describe what happens at the molecular level once equilibrium is reached--that is, once the solution is saturated with Cu(IO_3)_2. Why must some solid remain in contact with a solution of a sparingly soluble salt in order to ensure equilibrium? Describe how you are going to calculate the [Cu^2+] for the saturated solution of copper iodate once you know the absorbance value of the copper ion. How will you use this concentration to find the K_sp value for...
