If the flame turns green, you have boric acid (H3BO3). If the flame turns purple (you may only see this by holding looking through the cobalt blue glass), you have KCl. Sodium contamination can make this hard to see. Look through the cobalt blue glass. If the flame turns reddish-orange, you have Ca(NO3)2

Also, the acid that has no hydro prefix and ends in –ic acid has the same number of O as the –ate ion. The acid that ends in –ous acid has the same number of O as the –ite ion (one less than the –ic acid) The acid that starts with hydro and ends in –ic has no O.
