Explain when measuring pH during a titration. We have a buret containing NaOH (aq) of known concentration. Explain under the buret we have a beaker containing HCl (aq) of unknown concentration. Explain with a pH meter in the beaker that reads 1.30.
In which direction do you wait for the pH to change as NaOH is added to the HCl solution?
A) The pH will increase
B) The pH will decrease.
C) The pH will stay the same.
