What else can I help you with?
What happens when you add iodine crystal and chloroform?
iodine is soluble in CHCl3. Liquid become purple in color.
Is iodine soluble wih chloroform?
Yes, iodine is soluble in chloroform. Chloroform is a nonpolar solvent, and iodine is slightly soluble in nonpolar solvents like chloroform.
What is the equation of iodine between water and chloroform?
The equation for the reaction of iodine between water and chloroform is: I2 (iodine) + 2CHCl3 (chloroform) ⇌ ICl (iodine monochloride) + 2HCl (hydrochloric acid) + CHCl3 (chloroform).
What is the value of distribution coefficient of iodine between water and chloroform?
For Iodine in Chloroform & water, the distribution ratio is 250; hence at equilibrium, the iodine concentration in the chloroform phase is 250 times then in the water phase.
Is black crystals of iodine turning into purple vapour of iodine a physical change or a chemical change?
The transformation of black crystals of iodine into purple vapor of iodine is a physical change. This is because the change does not involve a change in the chemical composition of iodine; it only involves a change in the physical state from solid to gas.

What is dark violet iodine crystals.. is it a chemical change or not?
In order for something to be considered a change some sort of change must occur. A crystal is an object, not a type of change. Dark violet iodine crystals are pieces of relatively pure elemental iodine.
What is the value of distribution coefficient of iodine between water and chloroform?
For Iodine in Chloroform & water, the distribution ratio is 250; hence at equilibrium, the iodine concentration in the chloroform phase is 250 times then in the water phase.
Is the heating of iodine crystals a chemical or physical change?
It is a physical change (sublimation).
Is black crystals of iodine turning into purple vapour of iodine a physical change or a chemical change?
The transformation of black crystals of iodine into purple vapor of iodine is a physical change. This is because the change does not involve a change in the chemical composition of iodine; it only involves a change in the physical state from solid to gas.
What is iodine crystals sublime to make purple gas physical or chemical change?
The sublimation of iodine crystals to produce purple gas is a physical change. This is because the change in state from solid to gas does not involve a change in the chemical composition of the substance. The purple color of the gas is due to the absorption and emission of specific wavelengths of light by the iodine atoms.
What is the difference between iodine crystals and iodine solution?
Iodine crystals are solid, crystalline form of elemental iodine, while iodine solution is a liquid mixture of elemental iodine and either alcohol or water. Iodine crystals are typically used for storage and long-term preservation, while iodine solution is commonly used for disinfection and medical purposes.
Are iodine crystals a pure sub stance or mixture?
Iodine crystals are a pure substance.
Are iodine crystals a conductor?
Iodine crystals are very poor conductors of heat and electricity
Why chloroform is used in the assay of potassium iodide?
Chloroform is used in the assay of potassium iodide because it forms a complex with iodine liberated from potassium iodide in presence of acid, and this complex has a pink color that can be easily detected. This color change helps in monitoring the reaction and determining the concentration of potassium iodide in the sample.
