ʻOi aku ka ikaika o nā waiwai kemika, akā ʻoi aku ka paʻa ma mua o ka hao. He paʻakikī ke hoʻoheheʻe ʻia i ka ea ma ka lumi wela a ʻaʻole maʻalahi ke hana me ka nitric acid concentrated. Hiki ke ahi a hoʻopili me nā halogens ke hoʻomehana ʻia, e hoʻoheheʻe mālie i ka waika dilute. Hiki ke komo i ka nui o ke kinoea hydrogen.
