Sodium bisulfite is used during the extraction to procedure to react with unreacted aldehyde according to the following equation: a) Why is this done? Answer this question by explaining what would happen (and why) without bisulfite extraction versus with bisulfite extraction, assuming that not all of the aldehyde used during the reaction reacts. Focus on the isolated product from the reaction (2-methyl-3-heptanol) b) Saturated sodium bisulfite in water contains 42 g of sodium bisulfite per 100 mL of solution. What...
