For the following acids:
ii. HNO2
iii. HCN
a) What is the dissociation equation in an aqueous solution?
b)Give the KA expression for each of the acids.
c)Identify the acid-base pairs.

  • Chemistry -

    a)CH3COOH + H2O ==> CH3COO^- + H3O^+
    b) Ka = (H3O^+)(CH3COO^-)/(CH3COOH)
    c) CH3COOH is the acid/CH3COO^- is the base. H2O is the base/H3O^+ is the acid.
    The others are done the same way. Just remember the definition of a Bronsted-Lowry acid/base and you can't go wrong.
