10 there are eight alternating single and double bonds. This compound absorbs violet light and as a result it is perceived as yellow in colour. Conjugated double bonds are present in the molecules of all dyes and many other coloured organic compounds. Extended conjugated systems occur in several natural colouring matters, including carotene in carrots and fruit juices, and crocin which is found in saffron. Such compounds are not very substantive to fibres, however, and are unsuitable as starting points for dye synthesis.

Even liquid water undergoes Home 3· THE CHEMICAL PRINCIPLES OF COLORATION dissociation to some extent: about one water molecule in every 10 million molecules COO– dissociates. 5. Each positively charged hydrogen ion is accompanied by a H3N+ Cl– COOH negative wool number of positive and negative COOH charges in the solution are balanced. 7 The formation of salt linkages between a dye and a wool fibre: NaD represents the sodium salt of a large dye molecule acidic. 6). Other acids, such as ethanoic acid (acetic acid, CH3COOH), only partially dissociate in water and therefore are said to be weak acids.
