The success of this process has not only introduced a competitor which must eventually very much restrict the use of lead chambers, but one which possesses two important advantages, one in that it is more economical to manufacture a strong acid at once, thus doing away with concentration plants, and the other that it furnishes an acid which is free from arsenic. This may well be considered the greatest triumph of technical chemistry in the last decade.
