rthmjohn Posted April 10, 2006 Posted April 10, 2006 hmmm.... my chem gave us this test with the following question: will Cl2O give an acidic, basic, or neutral solution when dissolved in water? Write a reaction to justify your answer. I'm guessing it will make an acidic solution because it would make HCLO, right? What's the equation for this reaction? I'm guessing Cl2O + H2O <--> 2HClO, but is this right?
woelen Posted April 11, 2006 Posted April 11, 2006 Yes, you are right. You get hypochlorous acid. This is a very weak, but strongly oxidizing acid. This acid also is quite unstable. It slowly decomposes, giving chlorine, chloric acid and hydrochloric acid.
rthmjohn Posted April 12, 2006 Author Posted April 12, 2006 on this same take-home test i am asked how to calculate the pH of a solution of H2CO3 being only given the ionization constants for: H2CO3 <==> H(+) + HCO3(-) and HCO3(-) <==> H(+) CO3(2-) I don't know where to start. Can anybody give a hand? Does it involve using the ionization constant for the overal reaction: H2CO3 <==> 2H(+) + CO3(2-)?
