here is a question from a buffer post lab report for my chem lab.
"how does the buffer capacity of the two solutions change? that is over what range of strong acid/strong base volume is the ph of the buffer resistant to change? for your two data sets of buffer data, indicate the moles of acid or base that can be added in this range."
from our first derivative graphs of our combined hcl/naoh titrations, we determined the buffer limits to be:
solution 1: -10.00 ml hcl and 2.75 ml naoh
solution 2: -22.00 ml hcl and 2.10 ml naoh
how do i use these buffer limits to figure out the moles of acid and base that can be added in the buffer range? or do i not even use these buffer limits? i'm very lost.
