(a)
Interpretation:
The significance of the points at which the two curves meet in the given graph is to be determined. Also, the values of fraction and the pH from the given graph needs to be determined.
Concept introduction:
The curve of a titration graph is used to indicate the change in the pH of the solution as the change in volume of the mixture takes place due to the addition of the titrant. The volume of the chemical is an independent variable in the graph while the pH of the solution is a dependent variable as its value changes on the addition of more volume of the titrant.
(b)
Interpretation:
The curve for the carbonic acid is to be determined and also the number of intersection points at the corresponding pH values is to be determined.

- The titration curves for two acids with the same base are shown on this graph. (a) Which is the curve for the weaker acid? Explain your choice. (b) Give the approximate pH at the equivalence point for the titration of each acid. (c) Explain why the pH at the equivalence point differs for each acid. (d) Explain why the starting pH values of the two acids differ. (e) Which indicator or indicators, phenolphthalein, bromthymol blue, or methyl red, could be used for the titration of Acid 1? For the titration of Acid 2? Explain your choices.arrow_forwardWhat accounts for the discrepancy in pH? When you have already dissolved the computed masses of reagents for the buffer in an ample amount of distilled water, and upon checking the pH using the pH meter the pH is less than the target pH.arrow_forwardDescribe the changes in pH that take place during the titration of: (a) a weak acid with a strong base, (b) a weak base with a strong acid .arrow_forward
- For a titration to be effective, the reaction must be rapid and the yield of the reaction must essentially be 100%. Is Kc > 1, < 1, or ≈ 1 for a titration reaction? Kc is the product of all reaction products (choose from: Multiplied by, added to, divided by, subtracted from) the product of the reactants, with all concentrations of reactants and products raised to their respective stoichiometric powers. As the titration proceeds, the amount of reactants (choose from: Increases, decreases, remains the same) and the amount of products (choose from: Increases, decreases, remains the same). Because the value of the numerator is (Choose from much greater than, much less than, approximately equal to) the value of the denominator, the value of Kc will be (Choose from much greater than, much less than, approximately equal to)1 for an effective titration reaction.arrow_forwarda.)

How does this affect the calculation of the concentration of calcium hydroxide?arrow_forwardA buffer solution consists of 0,25 mol∙dm–3 acetic acid (HC2H3O2; Ka= 1,8 x 10–5) and 0,35 mol∙dm–3 potassium acetate (KC2H3O2). Calculate the pH of the buffer solution. A small quantity (0,050 mol) of solid KOH is added to 1 dm3 of the buffer. This quantity is so small that it does not affect the volume of the buffer.
