What reading level is Manual of Physico-Chemical Measurements book?
To quickly assess the difficulty of the text, read a short excerpt:
A float is constructed of a suitable specific gravity, a weighed quantity of the salt is introduced into a glass, and water is added until the float neither sinks nor swims. A weighing of the glass then gives the corresponding concentration. The solution to be investigated is then placed in the dry glass along with the float, and water is added as before. The weight of the whole solution multiplied by the concentration number, determined once for all, gives directly the quantity of salt present.... The only condition that needs attention is the temperature, which must be kept constant to about a twentieth of a degree.
Besides the specific gravity any other property which is suscep- tible of easy and accurate measurement may be used to determine the strength of a solution. The measurement of the electrical con- ductivity has been of service in the case of very sparingly soluble salts, as it permits the exact estimation of much smaller quantities of salts than either direct analysis or the determination of the specific gravity.
