Basic chem/math, but that 90% is really messing with my mind. I have the solution from princeton, but i'm not sure I quite understand. Thanks for the help
Let's use easier numbers to explain. So 90% of 100 units is equal to 90 units. Simple right?
Now, let's then re-write 0.1 as 0.100.
So now, 90% of 0.100 units is equal to 0.090 units. This new amount is what we're neutralizing. That means we're left with 0.010 units (since 0.100 units - 0.090 units = 0.010 units).
Convert 0.010 units (moles) to a pH scale.
0.010 --> 1.0 x 10^(-2), which is equivalent to a pH of 2.
On a side note, it's Thanksgiving! Relax and enjoy today.
