text: As shown in the tables infra (Tables 1 and 2), when the concentration of phosphoric acid is low and the concentration of hydrochloric acid is increased, a smaller amount of exchanger is required.
text: There are indeed many processes which lead to aqueous hydrochloric acid by-products but the concentration of the hydrochloric acid is usually very low -- 5 to 8% by weight.
text: Moreover, certain impurities originally present in the rock tend to be carried through into the product when the acid concentration is low, as in dihydrate process acid, which are insoluble in more concentrated acid and thus could be removed with the calcium sulfate if the product acid were more concentrated.
text: Additionally, the concentration of phosphoric acid is low as compared to the sulfuric acid concentration, and the relatively high sulfuric acid concentration depresses the calcium level in the liquid portion of the slurry.
text: If the concentration is too low, the resulting mixture will be either a solid or a gum, and hence not conducive for application to the surface to be soldered.
