The figure in the preceding exercise shows the pH curves for the titrations of six different acids with NaOH. Make a similar plot for the titration of three different bases with 0.10 M HCl. Assume 50.0 mL of 0.20 M of the bases, and assume the three bases are a strong base (KOH), a weak base with Kb = 1 × 10-5, and another weak base with Kb = 1 × 10-10.
Answer to relevant QuestionsRepeat the procedure in Exercise 65 for the titration of 25.0 mL of 0.100 M propanoic acid (HC3H5O2, Ka = 1.3 × 10-5) with 0.100 M KOH. What is an acid–base indicator? Define the equivalence (stoichiometric) point and the endpoint of a titration. Why should you choose an indicator so that the two points coincide? Do the pH values of the two points have to ...When a diprotic acid, H2A, is titrated with NaOH, the protons on the diprotic acid are generally removed one at a time, resulting in a pH curve that has the following generic shape: a. Notice that the plot has essentially ...The solubility of the ionic compound M2X3, having a molar mass of 288 g/ mol, is 3.60 × 10-7 g/ L. Calculate the Ksp of the compound. Nanotechnology has become an important field, with applications ranging from high-density data storage to the design of “nano machines.” One common building block of nanostructured architectures is manganese oxide ...
