Name: CHM 1202 Calculating pH of Acid Solutions – Reading Guide Strong Acids List and memorize the six strong acids shown in Figure 14.6. Calculate the pH of an 0.22 M solution of HBr. Remember: Strong acid solutions completely dissociate so the (acid] = [H,O’]! (ans. pH=0.66) Weak Acids What is the difference between a strong acid and a weak acid? Write the K. equation for HNO2 Write the K, equation for HC H302
For weak acids, an ICE table must be used to determine the equilibrium concentration of HO. Follow Example 14.14 to see how this is done. Create an ICE table for a 1.55 M solution of HF. HF (aq) HO (0) H,O* (aq) F (agi + Use this ICE chart to calculate the [H,O*1 and the pH of this solution. The K, for HF IS 3.5 x 10 Note: You may use the “x is small approximation”, but you should check your assumption. (ans. [H,01 = 0.0233 M and pH = 1.63) Percent ionization = Calculate the percent ionization for the 1.55 M solution of HF from the problem above. (ans. 1.50%) End of Chapter 14 Practice “Calculating pH of Acid Solutions Reading Guide” by Montgomery College is licensed under CC BY
