"You have taken it already and it is in your hands; now make the gift perfect for me by putting it on and saying nothing more." "My wedding gift!" repeated the Girl. Slowly she lifted the beautiful ornament and held it in the light. "I'm so glad you just force me to take it," she said. "Any half-normal girl would be delighted. I do accept it.
Such solutions are called !Normal Solutions! and contain such an amount of the reacting substance per liter as is equivalent in its chemical action to one gram of hydrogen, or eight grams of oxygen. Solutions containing one half, one tenth, or one one-hundredth of this quantity per liter are called, respectively, half-normal, tenth-normal, or hundredth-normal solutions.
This is particularly true if, in connection with the normal solution, the weight of substance for analysis is chosen with reference to the atomic or molecular weight of the constituent to be determined. The preparation of an !exactly! normal, half-normal, or tenth-normal solution requires considerable time and care.
It is, however, a comparatively easy matter to prepare standard solutions which differ but slightly from the normal or half-normal solution, and these have the advantage of practical equality; that is, two approximately half-normal solutions are more convenient to work with than two which are widely different in strength.
