How do you use titration calculations to find pH?

Answer 1

You can use the concentration from a titration to find pH by using pH = -log[#H^(+)#]

Finding -log(0.1) would yield the pH in this case, which is 1. This is because HCl is a strong acid that fully dissociates in water, leaving only H+(aq) and Cl-(aq) bound together. For example, if you find that the concentration of HCl is 0.1M.

You can also assume that all strong bases will dissociate fully. A 0.1M solution of NaOH will yield a pOH of 1. pOH = -log[#OH^(-)#].

The pH in the second example would be 13 because pH + pOH = 14.

To find pH in titration, use the formula pH = -log[H+]. Determine the concentration of H+ ions, usually given in molarity. Substitute the concentration into the formula to calculate pH.

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
