Sample 1 A student states “A solution of 4 M sulfuric acid (H2SO4) is a stronger acid than a 1 M solution of sulfuric acid.” Construct a well-thought out response to help this student improve his understanding. Sample 2 Draw and upload representation that shows 10 molecules of a weak acid dissolved in water with 20% ionization. Include only the water molecules that react, not the excess water molecules in the solution. Sample 3 You have conductivity meters in 1 M solutions of HNO3, HNO2, and HC2H3O2. The 1 M HNO3 light bulb is bright, the 1 M HNO2 light bulb is giving off some light, and the 1 M HC2H3O2 is very dim. Rank the solutions in order of acid strength based on this information. (Strongest, middle, weakest)
In Analytical Chemistry, we are conducting an Absorbance Lab using CuSO4 . 5H2O . In the lab we are conducting a calibration curve and as part of our prelaboratory procedure we are asked to calculate the molarity of dilutions made from a stock solution; however, I am unsure how the crystalline water affects this calculation or if it is simply a straight forward C1V1=C2V2 calculation. I would really appreciate the help! "Calculate the concentration for each solution that are prepared by the following: Molarity (M) 2.00 mL of stock diluted to 10.00 mL 4.00 mL of stock diluted to 10.00 mL 6.00 mL of stock diluted to 10.00 mL 8.00 mL of stock diluted to 10.00 mL The stock solution is .1000M CuSO4 5H2O.
