8. Why is the synthesis of potash alum classified as a redox reaction? 2Al(s) + 2KOH(aq) + 6H2SO4(aq) + 22H2O(1)→ 2KAI(SO4)2 12H2O(s) + 3H2(g) A) Aluminum metal is oxidized from a zero to +3 oxidation state B) Hydrogen ions (H+) are reduced to form hydrogen gas. C) Both A and B D) None of the above True or False Questions (0.5 each) 9. Potash alum is commonly used as an astringent and in the process of water purification. 10. The integrated rate law for a zero-order reaction is not [A] = -kt + [Ao]. 11. NaOH is added to the crystal violet solution as a catalyst for the reaction 12. During the titration of a diprotic acid with a strong base, there will only be one distinct equivalence point. 13. Potash alum is an example of a double salt. 14. In spectrophotometry, the Beer-Lambert law states that absorbance is inversely proportional to the concentration of the absorbing substance, and the path length of the sample.
