Consider the titration of 60.0 mL of 0.10 M HBr with 0.15 M KOH. Calculate the pH after 60.0 mL...

Question:

Titration and pH of a Solution:

To determine the pH value of a solution, we have to have the molar concentration of hydronium ions in the solution. If the concentration of hydroxide ions is known, then also the concentration of hydronium ions can be calculated. The following formulas are generally utilized to find the pH of a solution:

{eq}\begin{align} ~\text{ Molar concentration of a solution} &=\dfrac{~\text{ Number of moles of solute present in a solution} ~}{~\text{Volume of the solution} } \\[0.3cm] \rm p\rm{H} &= \rm -\log_{10}{[ \rm H^+]} \\ \rm p\rm{OH} &= \rm-\log_{10}{[ \rm OH^-]} \\ \rm p\rm{H} + \rm p\rm{OH}&= \rm14 \end{align} {/eq}
