1
Who was the founder of pH and how does the pH scale work?
Soren Sorenson - uses [H+] to measure pH
[H+] range from 10-1 to 10-14, pH is on a scale form 1 to 14
2
How do you convert between [H+] and pH.
pH = -log[H+]
[H+] = 10-pH
- a pH of 1 has 10 times as many H+ than a pH of 2
- to dilute a solution from pH 1 to 4, dilution required is 1000 times.
3
For mono-, di- basic acids, how does the acid conc. compare to [H+]?
For strong monobasic acids
[HA] = [H+]
For strong dibasic acids
2[HA] = [H+]
