What volume of 0.157M Nitric acid is needed to neutralize a 25ml of 0.1M NaOH? |
|
Answer» This is a titration curve question. I know that the initial PH of the hydrochloric acid is 1.65. I know that you can FIND the concentration of HCl by plugging it into the pH FORMULA. So, − log [ H + ] = 1.65
10 − 1.65 = 0.02239 = [ H + ] . However, that's as far as I've GOTTEN. I know the volume of the 0.1292 M NaOH is between 22 and 23 mL, but I can't seem to figure out how to find the exact value. Any help is greatly appreciated! |
