Why common salt cannot purified by sublimation?
Common salt, or sodium chloride, cannot be purified by sublimation because it has a high melting point (801°C) and does not sublime at normal temperatures and pressures. Sublimation is the process of a substance transitioning directly from a solid to a gas without passing through the liquid phase, which is not applicable to sodium chloride.
How is impure common salt purified?
Impure common salt can be purified through the process of recrystallization. This involves dissolving the impure salt in water, filtering out any insoluble impurities, and then allowing the solution to cool slowly so that pure salt crystals form. These crystals can then be separated and dried to obtain purified common salt.
Why Camphor can easily be purified by the process of sumlimation and common salt cannot be purified by sublimation?
Camphor is a molecular compound, with a molecular formula C10H16O. Because it is molecular and the solid is "held together" by inter-molecular forces it has a lower melting point 175 C and boling point 204C than sodium chloride mp 800+C. bp 1400+ C. Under gentle heating solid camphor has a a reasonable vapor pressure and sublimes (no melting or boiling required -as it is flammable care is needed.) Sodium chloride a giant ionic lattice held together by strong electrostatic bonds when under heated gently has virtually no vapor pressure and does not sublime.
Is KCL and NaCl is separated by sublimation?
Sodium chloride is not purified by sublimation.
What water salt or purified helps water?
purified
What method is used to separate ammonium chloride and common salt?
Ammonium chloride and common salt can be separated by sublimation, as ammonium chloride sublimes at a lower temperature compared to common salt. When heated, the ammonium chloride will turn into a gas and can be collected separately from the remaining common salt.
What water salt or purified helps plants grow?
purified
Does common salt sublime?
No, common salt does not sublime. Sublimation refers to the process by which a solid directly transforms into a gas without passing through the liquid phase. Salt will instead melt when heated, before eventually vaporizing.
What is purified salt?
Salt that has had any contaminates removed.
Does purified or tap water hold more salt?
It all depends on what you mean. Tap water has more salt than purified water but purified water can hold more salt if salt is added. There is more room, so to speak, for the salt ions to fit into a container.
Why should you use sublimation to separate the mixture of salt and ammonium chloride?
Because ammonium chloride can be removed from salt by sublimation (at a given temperature).
How you separate common salt and ammonium chloride?
One way to separate common salt (sodium chloride) and ammonium chloride is by sublimation. Heat the mixture and the ammonium chloride will turn into gas and can be collected as a solid when it re-condenses. The common salt remains behind as a solid.
