請問在化學上，提取(extraction)與提純(purification)有甚麼分別?
教科書把兩者分開舉例，並沒有作任何詳細解釋。請明自個中分別的朋友為小弟作詳細解釋。勞煩。
(請在解釋同時，從旁以英文作名詞解釋，因小弟是修英文的)

✔ 最佳答案
extraction means to get something that we want from asubstance. for example, we may like to get
some minerals in an ore. so we extract it from the ore.
but extraction doesn't mean that it is pure. it may contain
some impurities. so we have to purify them.
so purification means to get a pure substance from a
impure one.
