2 Objectives Discuss the characteristics of, and list in order of strength, hydrogen bonds, ionic bonds, polar and non-polar covalent bonds. Define cation and anion. List the chemical abbreviations for the principal elements of physiological interest. Define the term 'buffer' with respect to pH. Given a volume of solvent and the numbers of moles of solute dissolved in it, calculate the molar concentration of the resulting solution. Instead, we will consider selected concepts upon which much of the material covered in future lectures is based.
Ionic bonds tend to be stable except in water.
Polar covalent bond - one or more of the 'shared' electrons spends a greater percentage of time in the orbital of a region of the molecule. C. Catalysts are agents that accelerate the rate of a chemical reaction. The concentration of a solute is a measure of the amount of that solute dissolved in unit volume of solvent. Throughout the course we will refer to the 'concentration' of various compounds. Indeed, it is one of the most fundamental measures in all of biology and chemistry.
