Therefore, the concentration of the analyte can be determined by knowing the exact concentration of the titrant and calculating its consumption (volume) with a measurable endpoint. The titration reaction is, $\text{NaOH} (aq) + \text{KHC}_{8} \text{H}_{4} \text{O}_{4} (aq) \rightarrow \text{NaKC}_{8} \text{H}_{4} \text{O}_{4} (aq) + \text{H}_{2} \text{O}$, To calculate concentration, we need to know the amount of NaOH and the volume of solution in which it is dissolved. In a perfect titration, the endpoint and equivalence are identical. Titration of the sample requires 27.03 ml NaOH(aq). Schematically, \begin{align} & V_{\text{NaOH}}\rightarrow{c_{\text{NaOH}}}n_{\text{NaOH}}\rightarrow{\text{S(C}_{\text{6}}\text{H}_{\text{8}}\text{O}_{\text{6}}\text{/NaOH)}}n_{\text{C}_{\text{6}}\text{H}_{\text{8}}\text{O}_{\text{6}}}\rightarrow{M_{\text{C}_{\text{6}}\text{H}_{\text{8}}\text{O}_{\text{6}}}}\text{m}_{\text{C}_{\text{6}}\text{H}_{\text{8}}\text{O}_{\text{6}}} \\ & \text{m}_{\text{C}_{\text{6}}\text{H}_{\text{8}}\text{O}_{\text{6}}}=\text{16}\text{.85 cm}^{\text{3}}\times \dfrac{\text{0}\text{.1038 mmol NaOH}}{\text{1 cm}^{\text{3}}}\times \dfrac{\text{1 mmol C}_{\text{6}}\text{H}_{\text{8}}\text{O}_{\text{6}}}{\text{1 mmol NaOH}}\times \dfrac{\text{176}\text{.1 mg }}{\text{mmol C}_{\text{6}}\text{H}_{\text{8}}\text{O}_{\text{6}}} \\ & = 308.0 \text{ mg} \end{align}, $\dfrac{\text{176}\text{.1 g }}{\text{1 mol C}_{\text{6}}\text{H}_{\text{8}}\text{O}_{\text{6}}}=\dfrac{\text{176}\text{.1 g }}{\text{1 mol C}_{\text{6}}\text{H}_{\text{8}}\text{O}_{\text{6}}}\times \dfrac{\text{10}^{\text{-3}}}{\text{10}^{\text{-3}}}$, $=\dfrac{\text{176}\text{.1 g}\times \text{10}^{\text{-3}}\text{ }}{\text{10}^{\text{-3}}\text{ mol C}_{\text{6}}\text{H}_{\text{8}}\text{O}_{\text{6}}}=\dfrac{\text{176}\text{.1 mg }}{\text{1 mmol C}_{\text{6}}\text{H}_{\text{8}}\text{O}_{\text{6}}}$. Include the terms titration, neutralization, titrant, end point, equivalence point, indicators, analyte and titration curve. The volume of titrant added can then be determined by reading the level of liquid in the buret before and after titration. the titration, or the point where the analyte has been completely consumed by the titrant, is identified by the point where the pH changes rapidly over a small volume of titrant delivered. Have questions or comments? Starch can be used as an indicator for REDOX titrations using iodine as the titrant (iodine is a weak oxidising agent) because starch forms a blue complex with iodine. The endpoint appears suddenly, and care must be taken not to overshoot the endpoint. 9. Vr . 2 To plot titration curves of pH vs mL of titrant added. • This results in a buffer being formed - Henderson-Hasselbach equation. Eventually, all the acetic acid is consumed. 8. After the titration has reached the endpoint, a final volume is read from the buret. The reaction which occurs is, $\text{C} \text{H}_{3} \text{COOH} (aq) + \text{ NaOH} (aq) \rightarrow \text{ Na}^{+} (aq) + \text{CH}_{3} \text{COO}^{-} (aq) + \text{H}_{2} \text{O} (l) \label{2}$. In analytical chemistry, a standard solution is a solution containing a precisely known concentration of an element or a substance. If either the titrant or analyte is colored, the equivalence point is evident from the disappearance of color as the reactants are consumed.
