Add Sodium to distilled THF. If blue colour appears it is perfectly dry. Now you have to distill it in the rising apparatus. Dry THF collects in the stillhead
pH of 99.9% pure tetrahydrofuran is around 4.5 - 5.0 (Sigma-Aldrich)
Mineral oil is insoluble in water due to its nonpolar nature, but it is soluble in tetrahydrofuran (THF) as they are both nonpolar compounds. Therefore, mineral oil would likely be soluble in a solution of water and tetrahydrofuran.
A laboratory oven is used to heat, dry, and sterilize samples or materials in a controlled environment. It provides a consistent and stable temperature for various laboratory processes and experiments.
To prepare a sample of pure dry ammonium nitrate, dissolve ammonium nitrate in water to form a saturated solution, then allow the solution to cool and crystallize. Filter and dry the resulting crystals to obtain pure dry ammonium nitrate.
Yes, tetrahydrofuran (THF) is a polar solvent. It has a dipole moment due to its oxygen atom and is capable of forming hydrogen bonds with other molecules, making it a good solvent for polar compounds.
pH of 99.9% pure tetrahydrofuran is around 4.5 - 5.0 (Sigma-Aldrich)
You can prepare 13-dibromopropane in the laboratory from lower alkanes or alkyl halides using HBr in the presence of peroxide.
You have to ensure there is good ventilation when you prepare chlorine in a laboratory because chlorine is toxic so you need to ventilate it to avoid breathing it in.

yes
they dry it out
Yes, they did. Laboratory experiments showed them the results.
THF stands for tetrahydrofuran, which is a solvent commonly used in organic chemistry reactions. It is a heterocyclic compound with a cyclic ether structure.
We cant prepare it in lab. But there are aquas ammoni in lab.
