When we add an acid to water H+ ions are released and form H3O+. H3O+ is called:
1 point
As the concentration of H3O+ increases, what happens to the pH of the solution?
1 point
If the pOH is 3, what is the pH? *

A buffer solution resists changes in pH. This means if you add an acid or base the pH of the buffer solution won't change very much. Identify a buffer solution in the human body. *
Your answer
I preform a titration to determine the concentration of an unknown solution. I add 75mL of 1.0 M acid to 50mL of the unknown solution. At this point the solution is neutralized. What is the concentration of the unknown? Hint: use M1V1=M2V2.
