Just help with part B,i please!
2. (22 pts) In activity V you performed conductometric titrations of FeCl3 6H20 and CuCl2 2H20 with NaOH. Consider these titrations to accuately answer these questions (8 pts) Draw four separate pictures representing the molecular-level view of the solution in the beaker during the titration of either FeCls-6H20 or CuClz 2H20 (you do not need to draw pictures of both substances-just choose one substance for your pictures). In your pictures, use symbols (i.e. triangles, etc.) or atomic labels (i.e. Fe3, etc.) to represent the particles in solution. If you use symbols, clearly define your symbols with a legend. Do not use more than 15 particles/symbols in the picture. For the four pictures: a. i. First picture: Solution immediately after dissolving the solid li. Second picture: Solution after adding a small amount of NaOH but before the minimum in the titration graph i. Third picture: Solution at the minimum in the titration graph iv. Fourth picture: Solution after the minimum in the titration graph b. (6 pts) The reactions performed in activity V are generally called "double displacement reactions". If you are unsure what this means then quickly perform an internet search in order to answer the following questions: What are the products that are formed as each of these reactions takes place? If you could manipulate individual molecules and knew that you had 36 molecules of FeCls, how many molecules of NaOH would you need to completely react with the FeCla and how many molecules of each of the products would you form? i. ii. i. What about if you had 41 molecules of CuCl2?
