✦ Synopsis

S#u#~~~~ ivon salnfion. I)issolvc o. xo g iron wire in I o mt of concentrated hyclrockloric acid. Add I to z drops of 30% hydrogen peroxide. Add 10 ml of water; boil to decomposEir hydrogen peroxide. Dilute to I 1 with 8 stock soh~tion af I : I hydrochloric acid. One ml equals Q,X mg of iron. Hydrochloric acid soluGon (z :f). Prepare 20 1 (5 gal.) of x : x hydrochloric acid for use in all samples and standards. ~~~~-~~~~ ~~Ycu~~~ ~~~0~~~~.
