| Front | Colors of indicators in acidic and basic solutions: 1. Litmus paper - acidic & basic2. Phenolphthalein - acidic & basic |
| Back | 1. Litmus paper - acidic = red & basic = blue 2. Phenolphthalein - acidic = colorless & basic = pink -Note - color change noted at the endpoint |

| Front | VSEPR - Molecular Geometry • For trigonal bipyramidal (5 pairs) - know the main structure & know that every electron group that will be "plucked off" will be one-by-one from the main, central plane (the trigonal plane aka the 3 on the x-axis)• For octahedral (6 pairs) - know the main structure & know that the first electron groups to be “plucked off” will be one-by-one from the vertical aka y-axis (there’s only two) |
| Back | Trigonal Bipyramidal Example: see-saw will result if you pluck off electron pair on trigonal bipyramidal traditional shape Octahedral Example: square pyramidal actually looks like a square pyramid & if you take off 1 more off that you will be left with just the square on the same plane aka square planar

| Front | Cell potential - definition Is it an intrinsic or extrinsic factor? |
| Back | Cell potential - how much voltage exists between 2 half-cells (2 half-reactions) of a batteryIt is in intrinsic factor since the # of particles (mass, density, volume) do NOT matterEo of 3Na+ = Eo of Na+ |
