    About The water that sucked into the flask, does that means the volume of that water is equivalent to the volume of gas??

    I made diphenylketyl the other day from benzophenone and sodium metal in THF. Lovely blue colour. Don't know much else about it except there was a dark blue green solid that turned light yellow near colourless overnight in air

    Could you obtain the same result by mixing the acid and the alcohol and just let them sit for a couple of weeks?

    Hello, my English is so-so, but I have a question when you say something about a "very favorable insoluble salt to be produced and, in the presence of nitrate, which is a soluble silver salt, if chloride is available, leaving a gray colored solution whitish and definitely some silver chloride is formed. What is insoluble salt called?

    This is an interesting method for forming the diazonium compound. I usually drip solution of sodium nitrite into an acidic solution of aniline hydrochloride.

    Andrew, hi. I am here to do my brother's homework, as he is not strong in English. Lecturer asked him to translate and conduct same "experiment" in lab class. I could not think of the worst task(to watch and translate) to give to me on Saturday. but I enjoyed it. Keep going buddy, it was interesting for even someone who knows nothing :)

    I had a question about phenol solubility in water. Wouldn't the benzene group be considered a large nonpolar group that would hinder solubility in water? Similar to the 2-methylcyclohexanol ?
