I am a little confused on this question:

Write the formula unit and the net-ionic equations to describe the reaction between potassium hydrogen phthalate (KHP) and cesium hydroxide (CsOH). They want us to use KHC8H4O4 as the formula for (KHP), and HC8H4O4- to represent the hydrogen phthalate ion.

Am I just supposed to write a reaction equation?

Very confused.

Thanks

That's right, the net ionic equation is

HC8H4O4�?/SUP> (aq)  +  OH�?/SUP> (aq)   ––�?gt;   C8H4O42�?/SUP> (aq)  +  H2O (l)

Writing the "formula unit" equation, we have

KHC8H4O4 (aq)  +  CsOH (aq)   ––�?gt;   KCsC8H4O4 (aq)  +  H2O (l)

But the ionic compounds are completely dissociated in water:

K+ (aq)  +  HC8H4O4�?/SUP> (aq)  +  Cs+ (aq)  +  OH�?/SUP> (aq)   ––�?gt;   K+ (aq)  +  Cs+ (aq)  +  C8H4O42�?/SUP> (aq)  +  H2O (l)

Thank you

That is exactly what I did. Just confused on the wording. Thanks again.
