Page 165 - Whenever a metal reacts with an acid the first action consists in the replacement of the hydrogen of the acid by the metal. The hydrogen is liberated and a salt is formed. In the case of copper and sulphuric acid, however, the reaction does not take place at ordinary temperatures, and at higher temperatures the hydrogen which is first liberated acts upon the sulphuric acid reducing it to sulphur dioxide : — H2SO4 + H2 = 2 H2O + S02.
Page 330 - ... placed one at each end, and on the hearths of which the salt is completely decomposed. The charge of half a ton of salt is first placed in the iron pan, and then the requisite quantity of sulphuric acid allowed to run in upon it. Hydrochloric acid...
Page 14 - These cases illustrate what is known as the law of multiple proportions, which may be stated thus : If two elements, A and B, form several compounds with each other, and we consider any fixed amount of A, then the different amounts of B which combine with this fixed amount of A bear a simple ratio to each other.
Page 39 - The calorie is the amount of heat necessary to raise the temperature of one gram of water one degree centigrade.
Page 331 - By recent act of Parliament, the alkali makers are compelled to condense at least 95 per cent of the hydrochloric acid gas they produce ; and so perfectly is this condensation as a rule carried out, that the escaping gases do not cause a turbidity in a solution of silver nitrate, proving the absence of even a trace of the acid gas. After the mixture of salt and acid has been...
Page 354 - Slake the lime by the gradual addition of 6 parts of water, then add 30 parts of water, and stir occasionally during half an hour. Allow the mixture to settle, decant the liquid and throw this away. Now add to the residue 300 parts of distilled water, stir well, and wait a short time for the coarser particles to subside, and then pour the liquid, holding the undissolved lime in suspension, into a glass-stoppered bottle. When wanted for use, pour off the clear liquid.
Page 245 - ... and great care must be used not to inhale any of it. Allow the acid and zinc to work until the apparatus is free from air before adding the arsenic compound ; the gas escaping from the jet should be immediately ignited. (c...
Page 331 - ... do not cause a turbidity in a solution of silver nitrate, proving the absence of even a trace of the acid gas. After the mixture of salt and acid has been heated for some time in the iron pan, and has become solid, it is raked...

The Appendix, which gives (i) Instructions for equipping the laboratory ; (2) Directions for preparing all needed reagents ; (3) A complete list of working materials ; (4) The impurities found in commercial reagents ; (5) All the names by which reagents are known. The book is based upon plans and methods which have been employed in the author's laboratory throughout a series of years, and no work has been incorporated in the text or in the exercises that has not there...
