Discuss the pH method for determining acid strength. Show how to compute pH from the concentration of hydronium ions. Introduce the acid ionization constant for acids. Show how to arrive at the constant. Discuss why a strong acid has a particular number and its meaning. Work a few problems
Discuss Arrhenius acid modes. Introduce proton donor and acceptor. Discuss some examples of proton donors and acceptors, and why they are either acid or base molecules. Define monoprotic, diprotic and polyprotic. Show why some may be amphiprotic
Review Bronsted -Lowry acids. Introduce pH of a solution and relate it to the concentration of hydronium ions. Use the water constant Kw= conc. of hydronium x conc. of hydroxide ions to solve for concentration of one of the unknown. Define pH as the negative log of the concentration
Review electronegativity of of atoms. Determine differences between metals, not metals and metalloids as determined by their numbers. Outline how to present the correct Lewis Dot formula for a series of listed compounds. List all steps in the procedure for each type of determination.
Discuss how to determine the number of valance electrons in the valence shell in both A group and B group elements. Demonstrate by using a number of elements in the A group and then showing how to correctly determine the valence electron configuration. Show how to indicate the valance electrons for a B group, utilizing period numbers and ssubshell designations.
