Question

Draw the general titration curve for a strong acid titrated with a strong base. At the various points in the titration, list the major species present before any reaction takes place and the major species present after any reaction takes place. What reaction takes place in a strong acid– strong base titration? How do you calculate the pH at the various points along the curve? What is the pH at the equivalence point for a strong acid–strong base titration? Why? Answer the same questions for a strong base– strong acid titration. Compare and contrast a strong acid–strong base titration with a strong base–strong acid titration.

Short answer

The chemical reaction that occurs in a strong acid-strong base titration is a neutralization reaction

The pH at various points of the curve can be determined using the stoichiometric relationship between acid and base.

The pH at the equivalence point is pH=7.00

Step-by-step solution

Definition of titration curve

The plot of the pH of the analyte solution versus the volume of the titrant added as the titration progresses is defined as the titration curve

Explanations

The titration of a strong acid with a strong base or vice versa gives the pH of the final solution 7.00. A titration curve can be created for the titrations where initially there is more strong acid in the solution, and upon the addition of the base, the pH rises suddenly to a high value.

The titration curve is:

In a strong acid-base titration, a neutralization reaction occurs. After the neutral solution, no acidic or basic species remain in the solution. The litmus color remains unchanged when pH is checked using litmus paper.

At a given point of the titration curve, the exact pH can be determined using the stoichiometric relationship between acid and the base. The remaining amount of acid in the analyte is initial- x moles. This value can be used to calculate the H⁺ ion concentration of the analyte solution and, thus, the pH of the solution.

At a given point of the titration curve, the exact pH can be determined using the stoichiometric relationship between acid and the base. All the added base molecules react with the acid molecules present in the analyte sample. The pH is neutral at this point, which is equal to pH 7.
