What do hydrochloric acid sulfuric acid nitric acid phosphoric acid have in common?
They are all strong acids and they dissociate ( at least the first proton ) completely in solution.
Who first invented disinfectant?
Sir Joseph Lister/phenol.
Why add dilute nitric acid with silver nitrate to test for halide ions?
The nitric acid reacts with other ions that might precipitate with silver nitrate. Doing this first gets these other unwanted precipitates out of the way. If you are testing with Fluoride as your halide remember that silver nitrate does not precipitate with Fluoride, so no precipitate does not mean that halide ions are not present.
Is nitric acid an organic acid?
NO, nitric acid is not an organic acid. It is the first mineral acid to be made by scientists and chemists.
What is first aid treatment for nitric acid spill on a bare arm?
Flood the site with water while removing jewelry or clothing that may hold the acid in contact with the skin. Continue for a minimum of 10 minutes. Expect the burn to develop a bright yellow color as the nitric reacts with the protein in skin. You are always advised to contact medical assistance for a chemical burn. (I had a 1cm X 10 cm 70% nitric acid burn on Jan 17. Healed well by Feb 1 w/o medial intervention) Chem Cate

How are nitric oxide and sulfur dioxide involved in acid deposition?
These gases form acids (sulphuric and nitric acidsrespectively) by reacting with oxygen an water present in air the first rain of the season contains droplets of these acids and effect the all material which is hit by such rain.

What were the first plastics made of?
Two of the earliest plastics were:Bakelite = phenol formaldehydePolyurethane = urea formaldehyde

What is the anhydride of nitric acid?
Nitric acid does not form the anhydride but dinitrogen penta oxide is theoretical anhydride of nitric acid.2HNO3 = N2O5 + H2O==========No. From the Wikipedia article on nitrogen pentoxide:N2O5 was first reported by Deville in 1840, who prepared it by treating AgNO3 with Cl2.Therefore, nitrogen pentoxide is the anhydride of nitric acid.
How do you convert chlorobenzene into phenol?
You hit it with steam, and it will hydrolyze into phenol and hydrochloric acid. This isn't a real common way of making HCl, though; the chloralkali process that gives us sodium hydroxide also throws off hydrogen and chlorine, which can be mixed and exposed to UV light to give HCl. But as an educational setup, it's fine. Most people get their phenol the old-fashioned way, by oxidizing isopropylbenzene. A big reason for doing it that way is the byproduct of the reaction is acetone. If you condense acetone and phenol, you get bisphenol a, which is required if you want to make either polycarbonate (by reacting it with phosgene) or epoxy (by reacting it with epichlorohydrin). 'Course, you can also sell the acetone and phenol separately because there is great demand for both chemicals.

gives a green color
