Document Summary

Chapter 12: chemical calculations for solutions: solutions. Solution: a mixture that is homogenous at the molecular level. Components of a solution are the pure substances that are mixed to form the solution. The components don"t have to be solid and a liquid. There can be many types of solutions. Most common type of solution: solid dissolved into a liquid. Saturated solution: the maximum quantity of solute is dissolved. It is important to realize that the solubility of a substance is the maximum quantity that can be dissolved in a saturated solution at a particular temperature: molarity. The concentration of solute in a solution, describes the quantity of solute dissolved in a given quantity of solvent or a given quantity of solution. Molarity = moles of solute/liters of solution: electrolytes. Electrolytes: solutions that contain ions and conduct an electric current. Aqueous solutions that do not conduct an electric current are called nonelectrolytes.

THANK YOU!!!!!!!!!!!!!!!!!!!!!!!!

Consider the equilibrium reaction for the saturated solution of a salt, A B 3 : A B 3 (s)? A 3+ (aq)+3 B ? (aq) For each A B 3 formula unit that dissolves in water, the number of B ? ions is three times the number of A 3+ ions. In a saturated solution of the salt A B 3 , the number of formula units of the salt dissolved equals the number of dissolved A 3+ ions. If you know the concentration of the dissolved ions in a saturated solution, the solubility of the solute, S , can be calculated for the system. Solubility can be expressed as a molar concentration. The molar concentration or the molarity of the solution, M , is equal to the number of moles of solute per liter of the solution: molar concentration (M) = moles of solute volume of solution (L)

Question:

Part C Go to the Slightly Soluble Salts tab. Set the volume to 1.0Ã 10 ?16 L . Select the salt thallium sulfide from the dropdown menu. In the text box provided, set the total number of ions under the data for "cations" to 8 to make the solution saturated. Calculate the solubility in M of thallium (I) sulfide for a saturated solution. Express your answer numerically in moles per liter to three significant figures. I dont know which thalium sulfide it is so if you could do both i would appreciate it/

I can't seem to figure this one out. thank you!
