Caustic potash specific gravities

Or, pass nitrous acid gas, formed by acting on 1 part of starch TviUi 10 of nitric acid, through a solution of caustic potash, specific gravity 1.38, until it becomes acid then add a little caustic potash, so as to render it distinctly alkaline. It may then be kept in tho liquid form, or evaporated to dryness. ( Coren-wvider.)... 

Caustic potash, KOH, also known as potassium hydroxide and lye, is a hydroxide salt. It is found as a white solid in the form of pieces, lumps, sticks, pellets, or flakes. Potassium hydroxide may also be found as a liquid. It is water-soluble and may absorb water and carbon dioxide from the air. The specific gravity is 2.04,...
