Why make a chemical test....

Explanation:

...when you can easily take the melting points....

#"melting point,"# #"phthalic acid,"# #207# #""^@C#

#"melting point,"# #"oxalic acid,"# #189# #""^@C#

#"melting point,"# #"oxalic acid dihydrate,"# #101.5# #""^@C#

Of course, oxalic acid is a much stronger acid than phthalic acid, so you could test the acidities of an aqueous solution.....
