**Determine the pH of the Titration***Objective*: Calculate the pH at the point in the titration of 40.0 mL of 0.200 M HC₄H₇O₂ with 0.100 M Sr(OH)₂ after 10.0 mL of the strong base has been added. Given that the \(K_a\) for HC₄H₇O₂ is \(1.5 \times 10^{-5}\).**Titration Details:**- \(K_a\) Expression Setup: You are required to set up the expression for \(K_a\) based on your ICE table and definition. Avoid combining or simplifying terms.**Equation Provided:**\[ K_a = \frac{[0.0400 - x][x]}{0.0200 - x} = 1.5 \times 10^{-5} \]**Feedback Message (Incorrect Response):**- You have an incorrect expression for \(K_a\). Recall the general definition of \(K_a\) for the generic acid \(HA\) as indicated: \[ HA(aq) + H_2O(l) \rightarrow H_3O^+(aq) + A^-(aq) \] \[ K_a = \frac{[H_3O^+][A^-]}{[HA]} \]**Note**: You have 1 attempt remaining to correct the expression.

All of the acids start out at 0.1 M concentration and 25.0 mL volume. Choose all of the correct statements about these titration curves from the cholces below. The titration curve labelled "D" is generated by the strongest acid in the series. In the curves shown above the stronger the acid the less NaOH required for neutralization. The stronger the acid the more important is the pKa of the Indicator used for titration. The Ka of the acid which generates curve "C" is about 103 The weaker the acid the lower the pH of the neutralization point. The acid which generates curve "D" has the highest neutralization-point pH in the series.
