Question: Common Ion Effect On Acid Ionization How Is The Ionization Of A Weak Acid Affected By Other Ion Species In Solution Why The Ionization Constant (K) For A Weak Acid Allows Chemists To Predict The Concentration Of Ions In Solution At Equilibrium.At This Point You Have Learned To Solve These Types Of Problems If The Weak Acid Is Ionized In Water.
But. This problem has been solved See the answer. At this point you have learned to solve these types of problems if the weak acid is ionized in water. But what if the beaker contains a solution that already has some ions dissolved in it Can the weak acid still ionize to the same extent Docs the percent ionization change Model 1- Weak Acid Equilibrium Note: Proceed to Question 1 on the next page. Match each of the following descriptions with one of the beakers in Model 1. In each case assume that the change in volume as the solid(s) are added is minimal. Three of the beakers in Model 1 contain a common ion in solution. Which beakers in Model 1 contain a common ion b Consider the source of the common ion in each beaker. Does the common ion come from the weak acid molecules If no, explain the source of the common ion. Predict what will be in Beakers 1 and 2 when the systems in chose beakers reach equilibrium. Use particulate drawings below to communicate your predictions. Use the acid ion- ization constant to find the final concentrations of the molecular and ionic species in each beaker excluding water). Add this to Model 1. ![]() Calculat e the percent ionization of the weak acid in each beaker in Model 1 using the informa- tion from the tables. Add this information to Model 1. Does the presence of a common ion with a weak acid increase or decrease the percent ionization of the weak acid Support your answer with evidence from Model 1. According to Model 1, as the concentration of the common ion is increased, how does the per- cent ionization of the weak acid change Support your answer with evidence from Model 1. E10. Are the data in Model 1 consitent with LeChreliersPrinciple Support your anwer with ype cific examples from Model 1. Consider the four beakers below. Rank the beakers in terms of percent ionization of the weak acid from lowest to highest percent. Support your comparison with calculations similar to those in Model 1. The pH of the solutions in the four beakers in Model 1 was measured. Match cach pht with th correct beaker. H 0.7 Beaker pH 4.0 Beaker pH 2.4 Beaker pH 4.5 Beaker You have seen that the presence of a common ion in solution will decrease the percent ionization of a weak acid in solution. Provide two things that could be done to a solution to increase the percent ionization of a weak acid. Get more help from Chegg Get 1:1 help now from expert Chemistry tutors.
