    I thought i may as well put all the tests for ions in 1 easy printable sheet to learn.

    Please tell me if there are any mistakes.

    Be careful with the alcohols.

    The PCl5 test will show the presence of an -OH group, this can be confirmed as an primary OR secondary alcohol using potassium dichromate (VI) and aq.sulphuric acid (orange -> green). If you get a reaction scheme and it has the dichromate test and shows orange to green, it could be either primary or secondary alcohol, it really isnt a definitive test for either.

    I'm not sure about the "aldehyde smell" either. The only time a smell can probably lead you to the type of compound is with an ester.
