Is chloroform a heterogenous mixture or homogenous mixture?
Neither. Chloroform is a compound, which makes it a pure substance.
Is chloroform an element a compound or a mixture?
Chloroform CHCl3 is a compound.
How do you separate benzoic acid from a mixture of benzoic acid and toluene using extraction?
Make a solution of Sodium Hydroxide or Sodium Carbonate and do three to four solvent solvent extractions using the aqueous base and the mixture o benzoic acid and toluene. Because benzoic acid reacts with base to form the water soluble carboxylate ion, it will react and the dissolve in the aqueous solution. Upon separation of the two phases acidify the aqueous extract with dilute HCl, a white needle-like precipitate of benzoic acid will form when the solution becomes acidic. Simply filter the crystals, wash with cold water, and then recrystallize using a mixture of 50/50 water and methanol or some other suitable solvent.
How do you obtain iodine from a mixture of powdered iodine and ammonium chloride?
Iodine is not soluble in water but soluble in organic solvents; ammonium chloride is soluble in water. Method 1: dissolving of the mixture in water, filtering, washing of the filter, recovery of iodine from the filter Method 2: dissolving of the mixture in chloroform, filtering, recovery of iodine from the solution by air evaporation at room temperature
What is the eutectic temperature for benzoic and mandelic acid?
The eutectic temperature for benzoic acid and mendelic acid mixture is 105-106º C. This is usually about 60% mandelic acid and 40% benzoic acid.
What is the purpose of using sodium chloride in DNA extraction experiment?
if is the best known example mixture

Is sodium chloride a heterogeneous mixture?
No sodium chloride is not a heterogeneous mixture.
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.

How a mixture of sand and benzoic acid which is soluble in hot water might be separated to provide benzoic acid?
Sand is insoluble in water and can be easily filtered.
What is the eutectic temperature for benzoic and mandelic acid?
The eutectic temperature for benzoic acid and mendelic acid mixture is 105-106º C. This is usually about 60% mandelic acid and 40% benzoic acid.
How do you separate water from a mixture of chloroform and water?
Distillation, because chloroform and water have different boiling points.
Is sodium chloride a compound or homogeneous mixture?
NaCl (sodium chloride) is a compound, not a mixture.
