2. HCN molecules, H3O+, CN1−, and water
molecules
3. H2CN+, OH−, and water molecules
4. H3O+, CN−, and water molecules
5. CN+, OH−, and water molecules
6. HCN molecules and water molecules

  • Chemistry -

    HCN is a weak acid.
    HCN + H2O <==> H3O^+ + CN^-
    This equation tells you what is there. Note the arrow is a double one, the reaction in an equilibrium with some of both sides at equilibrium.
