Find the pH of 0.19 M CH3COOH. Ka = 1.74 x 10-5M.
1. I mixed 20 mL of .1M CH3COOH + 20 mL of .1M
NaCH3CO
2. I measured out the 10 mL of my buffer into a vial and
measured the pH of my buffer solution to be 4.95.
From there does that mean from my 10 mL of buffer, my moles of
acid is 1.12x10-5M and my moles of base from 10.0 mL of
buffer is 8.91x10-10M?
I got 1.12x10-5M and 8.91x10-10M from
this:
And how would I find the...
