Aim: How are solutions diluted to lower concentrations? QQ: Soluble/insoluble/slightly soluble? 1. MgCrO 4 2. AgI 3. Ba(NO 3 ) 2 Do Now: If a 200 mL solution is 6 M, how could I make 100 mL of a 3 M solution? Dilutions Stock Solution: solution with high concentration that needs to be diluted Volumetric Flask: precise glassware used to make solutions and dilutions M 1 V 1 = M 2 V 2 Keep the stock solution on one side and the desired solution on the other. Be consistent with units! Example: A solution is made by dissolving 30 g of NaCl in 150 mL of water. What is the molarity? Using that as a stock solution, how could you make 200 mL of a 0.05 M NaCl solution?
