August 12, 1950 Preparation of Na3 Rh(NO2)6 m.w. [molecular weight] NaNO2 = 69.01 m.w. RhCl3 = 209.3 a.w. [atomic weight] Rh = 102.9

One gram of commercial RhCl3 was dissolved in 75 cc. of 1 m. NaNo2 & 5 cc. of 6 m. HC2H3O2; the mixture was heated at 60-90 degrees for 5 minutes. (A.A. Noyes & W. C. Bray, A sysem of qualitative analysis for rare elements, The MacMillan Company, 1948)
