Overview

This historic book may have numerous typos and missing text. Purchasers can download a free scanned copy of the original book (without typos) from the publisher. Not indexed. Not illustrated. 1916 Excerpt: ...be used immediately. The weighed ammonium salt may be still further tested for impurities by volatilizing the weighed salt by gently heating the dish with the Bunsen burner and weighing the residue. 360. Standardization by Specific Gravity.--Standard solutions of acids, especially sulphuric acid, may be made with almost as high a degree of accuraoy as by the methods already given, by carefully taking the specific gravity of the concentrated acid and diluting a measured or weighed amount to a definite volume. The C. P. concentrated sulphuric acid should first be diluted to about 30%. Acid of this concentration is not hydroscopic, and the change in specific gravity with change in concentration is greater than with the stronger acid. The specific gravity is carefully taken at the standard temperature, 15 C, by means of a Westphal balance or carefully calibrated pycnometer. The greatest care should be taken to bring the temperature to exactly 15 C. with a tested thermometer. If the acid is to be measured out it must be kept at this temperature as carefully as when the specific gravity is being taken. This difficulty may be obviated by weighing the acid. This method has the additional advantage that the weight can be taken far more accurately than the volume, especially if it is corrected for air displacement. The weighing need not be made closer than a few milligrams, as an error of 10 mg. is negligible. The calculation is also very simple. The number of grams of acid required per liter for the solution to be made is divided by th percentage given in the table for the specific gravity found. The quotient multiplied by 100 is the number of grams of the concentrated acid to be weighed out and diluted to a liter. As the measuring out of concentrated hydrochloric a...
