QUESTION 10 Which is NOT an oxidation reduction equation? Edit: This question was inadvertently difficult. It's good practice, though. You have to assign oxidation number to all chemicals. Then pick out the one equation where th oxidation numbers don't change; i.e., they are the same to the right and left of the arrow.. However, there is another way. One of the equations is an acid base reaction, the reaction of a strong acid and a weak base. I rewrote it...
