f.p depression = (freezing point of pure solvent)-(freezing point of solution)
-------> 178.4-166.2=12.2

The process of separation f mixture of camphor and sodium chloride?
by sublimation
Which substance will sublime at 298K?
Co2(s) will sublime
Can sulfur sublime?
Yes, it is possible at temperatures between 25 0C and 50 0C. Besides substances such as naphthalene, ammonium chloride, iodine, dry ice, camphor and anthracene, sulphur also sublimes.
What are examples of flammable solids?
Flammable solids are solid materials that can subject to combustion if placed in a situation where friction or other sources may cause it to ignite. Examples of flammable solids are: Organic - cellulose, naphthalene, camphor, nitrate; Inorganic - lithium amide, sulfur, phosphorous, decaborane
What is example of sublimation in science?
Examples of sublimation are moth balls and dry ice, both of which vaporize from a solid without going to a liquid state. Ordinary ice and snow also does this to a limited degree, though not as much as melting and evaporating.An example of sublimation is dry ice, CO2 (s). Dry ice sublimates at room temperature creating the vapor effect that it is famous for.
Why does the freezing point decrease when naphthalene is added in camphor?
When adding a solute to a solvent, the freezing point decreases and is also known as freezing-point depression. Hence when naphthalene is added to camphor the freezing point decreases.
How would you separate alum camphor and sugar?
To separate alum, camphor, and sugar, you can use the following procedure: Dissolve the mixture in water: Add the mixture of alum, camphor, and sugar to a beaker containing some water. Stir the mixture until all the components have dissolved. Add ethanol: Add ethanol to the beaker and stir well. Alum will precipitate out of the solution due to its low solubility in ethanol. Filtration: Use a filter paper to separate the precipitated alum from the solution. This will give you a residue of alum and a filtrate containing camphor and sugar. Evaporation: Pour the filtrate into a clean beaker and heat it on a hot plate or evaporate it to dryness to evaporate the ethanol. This will leave behind a residue of camphor and sugar. Separation of camphor and sugar: Add water to the residue to dissolve the sugar and leave the camphor as a residue. Filter the mixture to obtain the sugar solution and the camphor residue. Recovery of camphor: To recover the camphor from the residue, you can use sublimation. Place the camphor residue in a clean and dry evaporating dish and heat it gently. The camphor will sublime and condense on a cool surface, such as a watch glass, which can be scraped to collect the pure camphor. This process will separate alum, camphor, and sugar from each other.
What is the percent strength of 1 pint of solution containing 56 g of camphor?
11.8 % steps are: 56 / 473.2 ( how much Liters in a 1pint )* 100= 11.8
A mixture of camphor and benzoic acid can be easily separated by?
Benzoic acid is more soluble than camphor in ethanol. The solution can be filtrated.
What is the depression of freezing point of camphor?
Examples include salt in water, alcohol in water, or the mixing of two solids such as impurities in a finely powdered drug. In such cases, the added compound is the solute, and the original solid can be thought of as the solvent. The resulting solution or solid-solid mixture has a lower freezing point than the pure solvent or solid did. This phenomenon is what causes sea water, (a mixture of salt (and other things) in water) to remain liquid at temperatures below 0 °C (32 °F), the freezing point of pure water.
Is tannic acid and glycerin soluble in camphor solution?
It is! You just have to heat the glycerin!
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
Is camphor crystalline or amorphous?
Camphor is a crystalline substance.
What are the elements in camphor?
camphor contains hydrogen,nitrogen,oxygen
What is a synonym for camphor?
2-Bornanone that is from synonyms.net/synonym/camphor
Sublimation process of sodium chloride and camphor?
sublimation of camphor
How can you separate the mixture of sugar and camphor?
Camphor will sublime when heated mildly (sugar will not). Heat the mixture mildly, collect the sublimate separately, cool the sublimate to get camphor.
