Your basic component fluorene separated from the acidic and neutral components by adding 3M HCl. Draw the balanced chemical equation for the reaction between HCl and the basic component. To isolate your basic component, you then added 6M NaOH which precipitated your basic component from solution. Draw the balanced chemical equation for this reaction. Draw the balanced chemical equations for the separation and isolation of the acidic component also. When drawing the equations, use the structure of your basic and acidic component. Fully expanded Lewis structures are not necessary for this question. You may use expanded, condensed, or line structures, provided they are neat and legible. If you could not identify one of your components, then pick an appropriate component from the list of unknowns.
