Recrystallization is a procedure aimed at improving the quality of an impure solid compound by making its saturated solution in a suitable solvent, whereupon the pure compound separates out as crystals (with time), leaving behind the impurities in the solution.The crystals so obtained maybe collected by filtration.
A difference of quality; the pure chemical compound is a refined compound, having a very low concentration of impurities.
no
It's called a mortar and pestle and is used to grind, crush and mix solids. In chemistry, trituration (reducing particle size by grinding) can be used to purify a compound containing soluble impurities. The compound is ground up using the mortar and pestle then is rinsed in a solvent in which the impurity will dissolve but the desired compound will remain.
Tap water is a mixture. It is water with some impurities.
Water (independent of forms) is a compound - H2O; tap water is of course water - but containing some minor impurities. And seawater, waters from lakes and rivers contain many impurities but remain water.
No, it is the compound sodium chloride, a pure substance.
Compounds and substances are practically synonyms; a compound or substance may be impure (contain impurities) or pure ( the impurities are only as traces or absent).
