1. © Carey Munoz First, fold your paper in half like this. Not this. pH, pOH, [H + ], [OH - ]

2. © Carey Munoz You need four “flaps.” Do not write these numbers on your flaps! To cut “flaps,” cut only the top half of the folded paper. 1234

3. © Carey Munoz There are four flaps of information. pH pOH[H + ][OH - ] A measure of acidity; the “power” of hydrogen ion A measure of basicity; the “power” of hydroxide ion The hydrogen ion concentration The hydroxide ion concentration

4. © Carey Munoz Under flap 1 – pH 1 2 3 4 If you are using a regular calculator, type in this way. [H + ]log+/-

5. © Carey Munoz Under flap 1 – pH 1 2 3 4 pH = -log[H + ] Remember scientific notation – use EE, E or exp button. Do not type x10 in your calculator If you are using a graphing calculator, type in equation exactly like this. -log[H + ]

6. © Carey Munoz Under flap 2 – pOH 1 2 3 4 If you are using a regular calculator, type in this way. [OH - ]log+/-

7. © Carey Munoz Under flap 2 – pOH 1 2 3 4 pOH = -log[OH - ] Remember scientific notation – use EE, E or exp button. Do not type x10 in your calculator. If you are using a graphing calculator, type in equation exactly like this. -log[OH - ]

8. © Carey Munoz Under flap 3 – [H + ] 1 2 3 4 If you are using a regular calculator, type in this way. # for pH +/-2 nd log

9. © Carey Munoz Under flap 3 – [H + ] 1 2 3 4 [H + ] = 2 nd log(-pH) If you are using a graphing calculator, type in equation exactly like this. 2 nd log- # for pH

10. © Carey Munoz Under flap 4 – [OH - ] 1 2 3 4 If you are using a regular calculator, type in this way. # for pOH +/-2 nd log

11. © Carey Munoz Under flap 4 – [OH - ] 1 2 3 4 [OH - ] = 2 nd log(-pOH) If you are using a graphing calculator, type in equation exactly like this. 2 nd log- # for pOH
