Sulfurous acid

Sulfurous acid (British English: sulphurous acid) is the chemical compound with the formula H2SO3. There is no evidence that sulfurous acid exists in solution, but the molecule has been detected in the gas phase. The conjugate bases of this elusive acid are, however, common anions, bisulfite (or hydrogensulfite) and sulfite.

Raman spectra of solutions of sulfur dioxide in water show only signals due to the SO2 molecule and the bisulfite ion, HSO3−. The intensities of the signals are consistent with the following equilibrium:

SO2 + H2O HSO3− + H+
Ka = 1.54; pKa = 1.81.

Aqueous solutions of sulfur dioxide, which sometimes are referred to as sulfurous acid are used as reducing agents and as disinfectants, as are solutions of bisulfite and sulfite salts. They are also mild bleaches, and are used for materials which may be damaged by chlorine-containing bleaches.

Question:i need three formulas for NO2 SO2 and CO2 i have searched for a good thirty minutes but i can' find any of them this is the question my teacher gave us find the chemical formulas online for Acid rain there are 3 types CO2 SO2 and NO2 we need the actual formulas ok thank you... so if i find how those chemicals are balanced then i should be fine?

Answers:SO2 + H2O = H2SO3 (Sulphurous acid). CO2 + H20 = H2CO3 (Carbonic acid) As for NO2 .. I've no idea. I don't think it reacts with water to make an acid. It may be that 2NO2 + H2O will give the two acids of HNO2 + HNO3 ...(Sulphurous & Sulphuric acids).. It balances OK but I'm not sure if it's correct..!!

Question:I need the Ionic name and Acid name for the following Chemical formulas 1) H2BO3 (aq) 2) H2SO4(aq) 3)HNO2(aq) 4)H2SO3(aq) 5) H2CO3(aq) 6)HCLO3(aq) 7)H2Cro4(aq) 8)HCN 9) H3PO4(aq) 10) HBr(aq)

Answers:1) H2BO3 (aq) You mean H3BO3 which is Boric acid or Hydrogen Borate (III) 2) H2SO4(aq) Sulphuric Acid or Hydrogen Sulphate (VI) 3)HNO2(aq) Nitrous Acid or Hydrogen Nitrate (III) 4)H2SO3(aq) Sulphurous acid or Hydrogen Sulphate (IV) 5) H2CO3(aq) Carbonic Acid or Hydrogen Carbonate 6)HCLO3(aq) You mean HClO3 Hypochloric Acid or Hydrogen Chlorate (V) 7)H2Cro4(aq) you Mean H2CrO4 Chromic Acid or Hydrogen Chromate (VI) 8)HCN Cyanic Acid or Hydrogen Cyanide 9) H3PO4(aq) Phosphoric Acid or Hydrogen Phosphate (V) 10) HBr(aq) Hydrobromic Acid or Hydrogen Bromide Remember the overall oxidation state is zero. Oxygen is always -2 and H is always +1 the remaining charge is the number after the name of the element in the anion ( negative ion)

Question:I'm working on a newspaper article about organic agriculture and I'm trying to find a list of chemical names (trinitrotriethylglycophospho-whatever) of commonly used manmade fertilizers to use in my lead paragraph after the opening sentence "Manure happens." :-) If there's a list of chemical names of manmade fertilizers you can point me to, I would be a happy camper.

Answers:I cannot answer your question, because we are not a farm that uses chemicals. We cannot use the word "organic," because we refuse to pay the Government to be allowed to use a word in the dictionary. I can tell you where to find a valuable source for your research, however. Crack open your local phone book. Look in the blue pages (government stuff). Find the listing for Ag Extension office. You can pay them a visit, and they will be able to help you answer many, many questions like that (if someone else does not answer the question for you on this forum). ~Garnet Homesteading/Farming over 20 years
