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.
What else can I help you with?
How separate the sand and camphor by sublimation process?
Sublimation of camphor occur faster by heating and sand remain.
What do you meant by sublimation also give example?
Sublimation is the process of direct transformation of a solid in a gas: examples are iodine, naphthalene, dry ice, camphor.
What are 2 solid substances that don't go through a liquid state when heated and go straight to gas?
Naphthalene and camphor the process is sublimation
Why camphor disappears after sometime when left in open?
Camphor disappears when left in the open due to sublimation, a process where a substance transitions from a solid directly to a gas without passing through the liquid phase. This causes the camphor to slowly turn into vapor and disperse into the air, gradually reducing its visible presence.
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 separate the sand and camphor by sublimation process?
Sublimation of camphor occur faster by heating and sand remain.
The process of separation f mixture of camphor and sodium chloride?
The mixture of camphor and sodium chloride can be separated by sublimation. Camphor can be sublimed by heating, leaving sodium chloride behind. The vaporized camphor can then be collected and allowed to solidify back into pure camphor.
What process you would use to separate camphor crystals and sand?
Sublimation
How do you separate camphor from chalk powder?
Camphor can be separated from chalk powder using sublimation. Heating the mixture will cause the camphor to sublime (convert directly from solid to gas) and leave behind the chalk powder. The camphor gas can then be collected and allowed to solidify back into crystals.
Sublimation process of sodium chloride and camphor?
In the sublimation process, both sodium chloride (table salt) and camphor can directly change from a solid to a gaseous state without passing through a liquid phase. This occurs when they are heated in a controlled environment with low pressure, causing them to vaporize and then condense back into solid form upon cooling. Sodium chloride sublimes at a high temperature, while camphor sublimes at a lower temperature.
What do you meant by sublimation also give example?
Sublimation is the process of direct transformation of a solid in a gas: examples are iodine, naphthalene, dry ice, camphor.
Why do camphor dance on water?
Camphor dances on water due to sublimation, a process where it transitions from a solid to a gas. As the camphor heats up on the surface of the water, it sublimes, causing the camphor to move erratically due to the release of gas. This movement creates the impression of dancing on the water's surface.
Why camphor disappears without leaving any residue?
Camphor disappears without leaving any residue because it undergoes sublimation, a process where a solid transitions directly into a gas without passing through a liquid state. This means that camphor molecules turn into vapor and escape into the air, leaving no solid residue behind.
What solid can turn into a gas without becoming a liquid?
This process is called sublimation. Some common substances that exhibit sublimation are dry ice (solid carbon dioxide) and camphor.
What are 2 solid substances that don't go through a liquid state when heated and go straight to gas?
Naphthalene and camphor the process is sublimation
Why camphor disappears after sometime when left in open?
Camphor disappears when left in the open due to sublimation, a process where a substance transitions from a solid directly to a gas without passing through the liquid phase. This causes the camphor to slowly turn into vapor and disperse into the air, gradually reducing its visible presence.
How can you separate salt and camphor?
Camphor is a volatile solid i.e. its vapour pressure becomes equal to the atmospheric pressure much below the melting point. But, common salt is non-volatile. Hence, camphor may be very easily separated from common salt by a physical process, SUBLIMATION! props to yahoo answers
