molybdic

Finally, the citric acid method is laid down as a means for estimating the phosphoric acid in phosphates of alumina. Recent investigations have fully proven the superiority of the molybdic process for such determinations.

That manganese and iron are associated by the strongest analogies is generally admitted, and the parallelism of nickel and cobalt is indisputable. Chromium serves to connect the ferric with the molybdic family, but appears to be more ferric than molybdic.
