Homework Help: Reaction of oxides

  1. Jul 5, 2009 #1
    1. The problem statement, all variables and given/known data

    Which of the following oxides reacts with water giving a mixture of 2 acids?
    (1) CO2
    (2) NO2
    (3) SO2
    (4) P2O5
    (5) ClO2

    2. Relevant equations


    3. The attempt at a solution

    I know that,
    CO2 would give carbonic acid only,
    NO2 would probably give nitrous + nitric acid(so this could be the answer?),
    SO2 would give sulphurous acid,
    P2O5 would give phosphuric(5) acid
    for ClO2,I don't know how it reacts with water.would we get HClO or/& HClO2 or/& HClO3 or/& even HClO4?

    Hope someone can help me determine the answer.

    Thank you.

    You are right about CO2, SO2 and P2O5, seems like it is a time to check the book or visit library to find details about ClO2 and NO2 reactions with water.

    Yes,how silly of me,i found the reactions easily on the web
    Although ClO2 is highly soluble in water,it doesn't hydrolise in water,
    and NO2 upon hydrolysis,would give NO + HNO3

    Thank you
