Hi there,
I totally understand what is happening and what they are asking
but I cannot get passed the math.
Can someone please break this question down for me? also the
data in the last two rows is in ML. Please specify what you mean by
unclear?
Buffer capacity has a rather loose definition, yet it is an
important property of buffers. A commonly seen definition of buffer
capacity is: “the amount of H+ or OH– that can be neutralized...
