The real dextrin is determined by inverting a portion of the filtered liquid with hcl, and then determining its reducing power.
Now get some hydrochloric acid (hcl) diluted with three parts of water.
According to the data of Hawks report, the free acidity, in term of hcl, is 1⁄12 per cent.
Find the bottle marked "hcl, dilute 1-3," in which the acid is already diluted.
Removal of lime from bone by hcl to show other substances and need for lime.
Of this ash, 25 per cent was soluble in water, while 50.6 per cent was soluble in hcl.
This boiling, however, is seldom needed, as the borate is soluble in hcl.
hcl being required in the above experiment to satisfy the greater combining power of the newly formed products.
From a mixture of hydrochloric acid (hcl) and marble are obtained a salt, water, and carbon dioxide, the desired gas.
Consequently, when lactic-acid fermentation is once developed a comparatively large amount of hcl is required to arrest it.
