Method for crystallisation
WebScore: 4.7/5 (41 votes) . Though crystallization separates the compound in almost pure form, when the crystals form some of the impurities may trap in it.By recrystallization method, these impurities can be removed to a greater extend. Normally the crystals are dissolved in very little amount of hot solvent and allowed to dissolve completely. WebIn this video we look at a very common and often challenging practical in Chemistry (which is also a frequent exam question). We explore how to use titration to determine the water …
