A cation vacancy paired with an anion vacancy is called Schottky defect. The Frenkel defect is an ion vacancy and a corresponding ion interstitial impurity. Other types of defects can exist. One particular type involves multiple Fe Fe Fe Fe oxidation states. Transiton metal atoms, such as iron, can have more than one oxidation state or charge. For example iron can exist as Fe*, Fe", or Fe*. If the oxidation state of an ion in a crystal changes, that is another type of defect. The figure below shows a crystal of FeO after one of these defects is formed. One of the iron atoms has been oxidized to a charge of +3 instead of the normal +2. You will use charge Fe Fe balance to determine the defects that form when the oxidation state of one atom is changed. Keeping this in mind answer the following with respect to the figure below: 11. What is the charge on the crystal before the defect is formed. 12. What is the charge on the crystal after the defect is formed.

Solder is an alloy containing the metals tin and lead. A particular sample of this alloy weighing 1.50 g was dissolved in acid. All of the tin was then converted to the +2 oxidation state. Next, it was found that 0.368 g of Na2Cr2O7 was required to oxidize the Sn2+ to Sn4+ in an acidic solution. In the reaction, the chromium was reduced to Cr3+ ion.1. Write a balanced net ionic equation for the reaction between Sn2+ and Cr2O72- in an acidic solution.2. Calculate the number of grams of tin that were in the sample of solder.3. What was the percentage by mass of tin in the solder? Can you answer these questions for me and sort of explain how you got the answer. Redox reactions are giving me the blues.
