Holderness A., Lambert J. Practical Chemistry 1973 torrent

Textbook in PDF format

This new edition has been revised throughout and reset in order to meet the requirements of recent changes in the syllabuses of examination boards, to make alterations in treatment and technique conform with modern practice and to anticipate where. possible changes are likely to occur in the near future. A few experiments have been deleted but many more included in this edition. Ionic equations are given for reactions more often. In Part I a new chapter gives a few electrical experiments and the chapters on solutions and rates of reactions have been expanded; reversible reactions have been separated from reactions that occur principally in one direction. In Part II transition elements have been taken to include all the d block elements. In Part III organic preparations can be done as before using apparatus that is corked or else standard-joint glassware. Aliphatic compounds containing a particular functional group are considered alongside their aromatic
counterparts. In Part IV, the volumetric analysis, there are new chapters on cerium(IV) salts and complexometric titrations. In Part V the instructions for inorganicqualitative analysis are only given once and it is left to the teacher to decide upon which scale the analysis is to be performed. SI units have been used throughout. In general the International Union of Pure and Applied Chemistry recommendations have been followed for nomenclature, although not in occasional instances where in my view comprehensibility will suffer. Alternative names are frequently quoted for inorganic and organic substances because if the nomenclature report of the ASE is accepted by any examining board, the attempt to make naming even more logical may, in the next few years, make the situation more
confused and exhausting than in the last few. I should like to take this opportunity to thank all who have suggested improvements to the two previous editions or who have helped in the preparation of this one. In particular I am indebted to the late Mr A. Holderness and to Mr J. S. Clarke for their valuable suggestions and advice. Finally, I wish to express my sincere thanks to the publisher’s managerial staff from whom I have received every assistance and encouragement
