Why is always a cotton plug inserted at the end of a funnel during sublimation of ammmonium chloride?
sublimation means conversion of solid to direct gaseous state , if you didn't put cotton plug then your ammonium chloride's vapours will go to atmostphere and your ammonium chloride wasted. And if cotton plug is not applied you can't see conversion of it's vapours to solid again
Why formalin is used in titration of ammonium chloride with sodiumhydroxide?
Formalin is used as a preservative in the titration of ammonium chloride with sodium hydroxide to prevent the loss of ammonia gas. Ammonium chloride reacts with sodium hydroxide to produce ammonia gas, which can escape into the atmosphere if not preserved. Formalin helps to stabilize and retain the ammonia gas in solution during the titration process.
What is the function of ammonium chloride in preparation of martius yellow?
wash the product.The work of ammonium chloride in preparation of martius yellow is to polarize the compound structure of the solution.this allows exchange of groups during dyeing.it also helps in formation of soluble salt which can be used as a dye for wool and other materials.
How do you determine integral heat of solution of ammonium chloride by the calorimeteric method?
To determine the integral heat of solution of ammonium chloride by the calorimetric method, you would dissolve a known mass of ammonium chloride in a known volume of water in a calorimeter. Measure the temperature change that occurs during the dissolution process to calculate the heat absorbed or released. Use the formula q = mcΔT, where q is the heat, m is the mass of the solution, c is the specific heat capacity of the solution, and ΔT is the temperature change.
Is ammonia gas liberated upon heating ammonium sulphate with hydrochloric acid?
Yes, ammonia gas is liberated when heating ammonium sulfate with hydrochloric acid due to the reaction between the ammonium ion (NH4+) and the chloride ion (Cl-) which forms ammonia gas (NH3) and water (H2O).

Why you use ammonium chloride and ammonium carbonate in lysis buffer for DNA extraction from blood?
Ammonium chloride is used to lyse red blood cells in the blood sample, releasing the DNA. Ammonium carbonate helps to stabilize the DNA and prevent degradation during the extraction process. Together, they create an optimal environment for efficient DNA extraction from blood samples.

What are the buffers used in complexometric titration?
Buffers commonly used in complexometric titrations include ammonium acetate-acetic acid, ammonia-ammonium chloride, and potassium hydrogen phthalate. These buffers help maintain a relatively constant pH during the titration process, ensuring accurate and precise results.
How do you obtain iodine from a mixture of sodium chloride and iodine?
Iodine is not soluble in water but soluble in organic solvents; sodium 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
Why chloride ions are discharged at anode instead of hydroxide ions during the electrolysis of brine?
Chloride ions have a lower standard reduction potential than water, making them easier to oxidize at the anode compared to hydroxide ions. Therefore, chloride ions are preferentially discharged at the anode during the electrolysis of brine.
What do you call the solid substance form during sublimation?
You may have your terms backward. Sublimation is the disappearance of the solid phase material in favor of the vapor phase material. No solid substance is formed during sublimation.
What is the use of asbestos sheets in sublimation?
Asbestos sheets were previously used in sublimation to prevent overheating and spread heat evenly during the transfer process. However, asbestos is now known to be a health hazard, so it is no longer recommended to use asbestos sheets in sublimation. Instead, alternatives like silicon sheets or Teflon sheets are used for a safer transfer process.
Which phase change occurs during sublimation?
solid - gas
