Acids and Bases be specific in terms of H+ and OH- concentrations – Water why is it neutral? – How does pH change in an acid or a base What is buffer? Compare and contrast: Reactants vs. Products Endothermic vs. Exothermic reactions Describe how enzymes work. Inorganic Vocabulary Review Sections 2.1 and 2.2 Section 2.1: The Nature of Matter Anion refers to the number of protons Atomic Mass sum of protons and neutrons Atomic number positive subatomic particle Cation negative subatomic particle Covalent bond subatomic particle with a neutral charge Electron electrons are transferred from one atom to another. Ion refers to outer energy electrons Ionic bond when an atom gains or loses electrons Isomer electrons are shared between atoms Mass number the same molecular formula, different arrangement of atoms Neutron weighted average of the isotopes of an element Proton gains electrons to form a negative charge Valence loses electrons to form a positive charge Section 2.2: Properties of Water Acid Polar Molecule Adhesion Solute Base Solution Buffer Solvent Cohesion Suspension Hydrogen bonds Hydrophilic mixture in which all the components are evenly distributed Hydrophobic compound that produces hydroxide ions (OH-) in solution
