A monoprotic weak acid, HA (K, = 1.78 × 104), was titrated against NaOH. A 50.00-mL of 0.04870 M HA sample was titrated with 0.1000 M KOH. How much volume (mL) of titrant (NaOH) is needed to reach the equivalence point? а. Establish the stoichiometric ratio. Calculate the volume using the titration values and stoich ratio. b. What is the pH of the solution at the end/equivalence point? Create a hypothetical ICE table for the neutralization reaction. Use the Ka value to solve for the pOH/pH. Some conversion and equilibrium relationship may be necessary or needed. С. What indicator should be used for this titration analysis? And what color change may be observable? And why did you choose this indicator? You may use the table or chart from the modules or slide.

A titration of 40.0 mL of a sulfuric acid (H₂SO₄) solution of unknown concentration with a standardized 1.55 M Ba(OH)₂ solution requires 23.0 mL to reach the second equivalence point. What is the concentration of the H₂SO₄ solution?
Methyl Orange and phenolpthalein are common chemical indicators often used in titrations. What is the role of a chemical indicator? A substance added to a reaction that provides the proper environment for the reaction to move forward. A substance consumed in a reaction that changes the rate of the reaction. A substance that gives a visible sign, usually a color change, when a specific reaction condition is reached. A chemical indicator is necessary for the neutralization reaction between a strong acid and strong base to go to completion.
