These alkaline properties are characteristic not only of a sodium hydroxide solution, but of the solution of any soluble base. A base is obtained when a metallic oxide combines with water, and sodium hydroxide is one of the strongest bases. 225. Neutralization. When a solution of sodium hydroxide is added little by little to a solution of any acid,--let us say sulphuric acid, so as to have a concrete example,--it is found that the acid properties grow less and less marked until at a certain point they disappear altogether; addition 1 This is sometimes called sodium monoxide when it is wished to distinguish it from the peroxide. Otherwise, sodium oxide always means this oxide. CALCIUM OXIDE AND CALCIUM HYDROXIDE 213 of any further sodium hydroxide imparts the characteristics of a base to the whole solution. At the exact point at which the acid properties have disappeared and the basic properties have not begun to appear the solution is neutral, just as pure water is neutral. The process of just destroying acid properties by the careful addition of a base is known as neutralization; likewise the reverse process, that of exactly removing all basic properties by carefully adding an acid, is neutralization. In the above process of neutralization exactly two moles of sodium hydroxide must be added to destroy the acid properties of each mole of sulphuric acid, or, in other words, one molecule of sodium hydroxide for each acid hydrogen in a molecule of sulphuric acid. If the neutralized solution is evaporated, it is found that after all the water is driven off a solid white substance is left, which is sodium sulphate. The reaction of neutralization may be formulated: 2 Na0H + H2S04 2 H20 + Na2SCv...
