The definition of a strong Base vs. weak base is....
Strong Bases dissociate completely, where weak bases only partially dissociate (same is true regarding strong Acids versus weak Acids)
500
A solution with a pH of 1 is how many more times acidic than an solution with a pH of 4?
Up the pH scale by 4-1 (therefore 3), the pH scale is 10X10X10 or 1000 times more at pH 1 then pH 4.
500
How many moles of HCl must be prepared needed to prepare 1 L of a solution with a pOH of 12?
.01 moles
(first get pH by subtracting pOH from 14, get H+ concentration using [H+]=10-pH and multiply by liters (1 in this case)
