What reading level is A Short Course in Qualitative Analysis book?
To quickly assess the difficulty of the text, read a short excerpt:
Cd.
Metallic cadmium dissolves readily in nitric acid, and the solution contains nitrate of cadmium, Cd(NO 8 ) 2 . Sulphydric Acid and Ammonic Sulphide precipitate cadmium compounds as the sulphide, CdS, lemon yellow. This is insoluble in ammonic sulphide and potassium cyanide, but readily soluble in hot dilute sulphuric or nitric acid.
Sodic and Ammonic Hydrates precipitate com- pounds of cadmium as the hydrate, Cd(HO) 2, very readily solu- ble in a slight excess of ammonic hydrate, but insolu...ble in sodic hydrate.
When compounds of cadmium are mixed with sodic carbon- ate and exposed on charcoal to the inner blowpipe flame, the charcoal becomes covered with an incrustation of yellow or brownish-yellow oxide of cadmium, CdO.
Mix together mercuric chloride, cupric sulphate, and the nitrates of bismuth and cadmium, and add sulphydric acid until the metals are completely precipitated. Filter, and wash the precipitates with a little water ; spread the filter out ; scrape the precipitate from it, and heat the precipitate gently in a porcelain dish with strong nitric acid until red fumes cease to be given off ; then add a little water and boil for a few minutes.
