Groves bat-tery contains zinc in dilutedsulphuric acid, and plati-num in nitric acid; Bun-sens is like Groves, exceptthat carbon is substitutedfor platinum. Both arevery powerful and avoid the annoyance ofthe fumes of hyponitrousacid, a mixture of bichro-mate of potassium and sul-phuric acid (of each fourparts) and water (eighteenparts) may be substitutedfor the nitric acid in theThey are seldom used for purely Flo.
