Calculate the moles of HCI that must be added to 100.0 mL of a solution that is 0.20 M in HCO₂H and 0.30 M in NaCO₂H to result in a pH of 2.95. You may assume there is no change in volume of the solution upon addition of HCI. The solution is at 25 °C where Ką for HCO₂H is 1.8 x 10-4 Enter your response in moles with no units, and use the correct number of significant figures.

Table 13-4 lists the stepwise Ka values for some polyprotic acids. What is the difference between a monoprotic acid, a diprotic acid, and a triprotic acid? Most polyprotic acids are weak acids; the major exception is H2SO4. To solve for the pH of a solution of H2SO4, you must generally solve a strong acid problem as well as a weak acid problem. Explain. Write out the reactions that refer to Ka1 and Ka2 for H2SO4. For H3PO4, Ka1 = 7.5 103, Ka2 = 6.2 108, and Ka3= 4.8 1013. Write out the reactions that refer to the Ka1, Ka2and Ka3equilibrium constants. What are the three acids in a solution of H3PO4? Which acid is strongest?
