Chapter 5: introduction to reactions in aqueous solutions. Significance of water energy, health and environment. No single measure would od more to reduce disease and save lives in the developing world than bringing safe water and adequate sanitation to all un secretary-general kofi annan, 2003 international year of. Water is probably the only natural resource to touch all aspects of human civilization from agricultural and industrial development to the cultural and religious values embedded in society koichiro matsuura, Energetically favorable h2o-solute interactions: h-bonding (dipole-dipole) with solutes (o-h, n-h, c=o, +/-ion-dipole forces. Water auto-ionization: water is amphoteric and conductive. Ions conduct electricity because the ions move essentially independently of each other, each one carrying a certain quantity of charge. Nonelectrolyes solutes that do not provide ions when dissolved in water: eg/ lamp fails to light up. Electrolytes soutes that provide ions when dssolved in water.
