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.
HCN is mixed with water. Which is the best
description of what you would expect to find
in the solution?

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
