Production of Citric Acid
It is an organic carboxylic acid and can be extracted from the juice of citrus fruits by adding calcium oxide to form calcium citrate, which is an insoluble precipitate that can be collected by filtration; the citric acid can be recovered from its calcium salt by adding sulfuric acid.
Explanation:
Mrs Meador, because the water cycle is continuous and therefore has no clear end or beginning
Aspirin(3) was synthesized by esterification reaction of salicylic acid(1) with acetic anhydride(2) catalyzed by aluminum dihydrogen tripolyphosphate/loaded sulfur diatomite. The effects of materials ratio[r = n(2) ∶ n(1) ],reaction time,temperature and catalyst amount on the yield of 3were investigated by the single-factor experiments. The results showed that the four main factors influencing the yield of 3 are in the following order: r reaction time reaction temperature catalyst amount. Under the optimum reaction conditions[1 was 50 mmol,the catalyst amount was 5%,r was3. 14,at 81 ℃ for 40 min],the yield was 88. 6%. The yield still reach 83. 3% after reuse for five times of the catalyst
Answer:
B
Explanation
Salt water is a solution where the salt completely dissolves therefore is is homogeneous. Solvent is the liquid (water) that dissolves the solute (salt).
