CHEM 1061 Chapter Notes - Chapter 4: Sulfuric Acid, Nitric Acid, Spectator Ion
Document Summary
Solution concentration and the role of water as a solvent. Solute: dissolved in a larger quantity of another. Uneven distribution of electron charge and bent molecular shape will create a polar molecule. Water separates ions by replacing these attractions with others between several water molecules and each ion. Dissolution: attractions between each type of ion and several water molecules outweigh the attractions between the ions themselves. When an ionic compound dissolves the flow of electric current current increases dramatically. Current flow implies the movement charged particles. Covalent compounds do not dissolve in water. Concentration: quantity of solute dissolved in a given quantity of solution (or of solvent) Shows all the reactants and products as if they were intact, undissociated compounds. Shows all the soluble ionic substances as they actually exist in solution, where they are dissociated into ions. Spectator ions: present in the reactants but don"t change the actual reaction.
