Homework question J15 asks for the chemical equation of a proton transfer of a cation or anion with water
For example, a) NaC6H5O
How do you write this equation? The answer in the back of the book doesn't include Na in any part of the equation either.

Essentially, the question is asking you to write the proton transfer from water to the anion, or from the cation to water. Anions will accept protons and act as bases, while cations will donate protons and act as acids.

C6H5OH(aq) + H2O(l) <--> C6H5O-(aq) + H3O+(aq)
The essence is to treat H+ as a proton and form H30+
