Unformatted text preview: -Pure water does not conduct electricity because there are not enough ionic species for electricity to flow through. It is not an electrolyte.-Adding an electrolyte to water makes enough ions for electricity to pass through-Water is a good solvent for ionic compounds and for poplar covalent compounds(covalent molecules with polar bonds.) -If it contains an o-h bond it is said to have a polar covalent bond-If it has a strong intermolecular interactions you can dissolve in water-Water + ethanol = complete mixing-Water + sucrose = some mixing-Nacl = strong electrolyte-Sucrose = non-electrolyte -Both of these are very soluble in water why?-Sucrose has covalent bonds and when its dissolved in water the molecules remain intact and do not dissociate into ions. So it cannot be an electrolyte because electrolytes need ions. Redox reactions-Electron loss = oxidation-Electron gain = reduction-...
