Answer» Answer: In normal life we rarely come across pure substances. Most of these are mixtures containing two or more pure substances. Their utility or importance in life depends on their composition. For example, the properties of brass (mixture of copper and ZINC) are quite different from those of German silver (mixture of copper, zinc and nickel) or BRONZE (mixture of copper and tin); 1 part per million (ppm) of fluoride ions in water prevents tooth decay, while 1.5 ppm causes the tooth to become mottled and high concentrations of fluoride ions can be poisonous (for example, SODIUM fluoride is used in rat poison); intravenous injections are always dissolved in water CON |
