Calculating pH & pOH Concentration of H+ ions vs pH o Would a low pH have a high concentration of H+ ions or low concentration of H+ ions? (hint: low pH means acidic) o Would a high pH have a high concentration of H+ ions or low concentration of H+ ions? Concentration of OH- ions vs pH o Would a low pH have a high concentration of OH- ions or low concentration of H+ ions o Would a low pH have a high concentration of OH- ions or low concentration of H+ ions Loose Ends: Polarity: This is more like a scale (like the pH scale) where you can be nonpolar, slightly polar, kind of polar, and REALLY polar. The like-dissolves-like principle still applies: slightly polar dissolves slightly polar really well and really polar dissolves really polar. This slightly-kinda polar is sometimes called “polar covalent”. (Water is polar covalent, which is STILL polar) Covalent bonds: We didn’t spend a lot of time on these. As far as properties are concerned, they are (generally) the opposite of ionic. If ionic is strong, covalent is weak. If ionic has high melting/boiling point, covalent has a low melting/boiling point. Ionic can conduct electricity (electrolyte), covalent compounds generally cannot.
