The problem I'm having is plotting the information on the charts. I read
through the Whitman and Modern books that I have but still having trouble
understanding it. I'm also dsylexia so learing this is a little bit harder
on me.

Are you talking about Mollier or pressure-enthalpy charts? Acid
concentration is not generally needed for HVAC. Search "Mollier
diagram" or "pressure enthalpy charts". Good luck
