Weak electrolytes are those electrolytes which in water solutions dissociate only partially, giving ions and which are in equilibrium with undissociated molecules. Their water solutions conduct electric current weakly. For example, acetic acid partially dissociates into acetate ions and hydrogen ions, so that an acetic acid solution contains both molecules and ions.
Weber (Wb) is the SI derived unit of magnetic flux. The weber is the magnetic flux which, linking a circuit of one turn, produces in it an electromotive force of one volt as it is reduced to zero at a uniform rate in one second (Wb = V·s). The unit was named after the German scientist W.E. Weber (1804-1891).
White light is a mixture of lights of all colours. If white light is passed through a glass prism or an optical lattice, it is separated into several colours (the visible light spectrum).
White spirit (mineral spirits, petroleum spirits) is a paraffin-derived clear, transparent liquid which is a common organic solvent used in painting and decorating.
X-ray crystallography is a determination of a three dimensional arrangements of atoms in a crystal by analysis of X-ray diffraction patterns.
X-ray spectrum is a set of characteristic X-ray frequencies or wavelengths produced by a substance used as a target in an X-ray tube. Each element has a characteristic X-ray spectrum, and there is a strong correlation between atomic number and the frequencies of certain lines in the X-ray spectrum.
Qualitative analysis involves determining the nature of a pure unknown compound or the compounds present in a mixture. Qualitative inorganic analysis is used to separate and detect cations and anions in a sample substance. According to their properties, cations are usually classified into six groups. Each group has a common reagent which can be used to separate them from the solution.
