Kerl states that if all the silver is to be dissolved from gold by one boiling with nitric acid the amount of silver must be at least eight times the weight of the gold. When the proportion, 1:2½, is parted, the resulting gold is left as a porous sponge, if dilute acid is used for the first treatment.
