Please read carefully and thank you so much in advance.
In an experiment where Glacial Acetic Acid (the Carboxylic Acid) and 1-Butanol (the Alcohol) react with concentrated (18M) Sulfuric Acid (H2SO4), then adding water to pass through this mixture and draining the bottom aqueous layer, then doing the same with saturated sodium bicarbonate (NaHCO3) (draining bottom layer), and finally with saturated sodium chloride (NaCl) (draining bottom layer), some Anhydrous Sodium Sulfate (Na2SO4) is added to remove the water from the product. The final product should be Butyl Acetate.
The overall reaction should look like this:
Glacial Acetic Acid + 1-Butanol --> Butyl Acetate
or like this
Chemical Formula of overal reaction:
CH3COOH + C4OH10 --> C6H12O2
1. Butyl acetate was purified by distillation. Please answer the following questions regarding distillation:
b.) If residual water was present in crude butyl acetate before it was distilled, would the distillation still effectively purify butyl acetate? Explain. Note that, upon distillation, a residual (i.e. trace) amount of water will not affect a noticeable response from a thermometer. (1 Mark)
