Remember, Molarity and Concentration are the same thing. The formula is Moles of Solute/Liters of Solution.
We also took notes about a pH Scale.
It is a scale that determines how acidic or basic a solution is.
It ranges from 0 to 14.
Below 7- Acid
7- Neutral
Above 7- Base
We can use mathematical expressions that have been determined experimentally to solve for concentrations, plt, and pOH.
1. pH= -log [H+]
2. pOH= -log[OH-]
3. pH+pOH=14
4. [H+]=10^(-pH) <- this is how you find the molarity of the acid
5. [OH-]=10^(-pOH) <- this is how you find the molarity of the base
5. [OH-]=10^(-pOH) <- this is how you find the molarity of the base
just use these formulas to help with the homework... that was basically all we talked about.
I would personally like to go over the reason why we keep circling OH and H in the problems. I get that it has a certain meaning, but I wasn't there that day so I am out of the loop. Thanks!
