pH and Percent lonization of a Weak Base < 23 of 30 > Review 1 Constants Periodic Table Ammonia, NH3, is a woak base with a K, value of 1.8 10 6 a Part A The degree to which a weak base dissociates is given by the base-ionization constant, K. - For the generic weak base, B B(aq) + H20(1) - BH+ (aq) -OH- (aq) this constant is given by BHOH K. ВІ B What is the pH of a 0.390 M armonia solution? Express your answer numerically to two decimal places. View Available Hint(s) ( VO AED ΑΣά ? x 100% Strong bases will have a higher Ki, value. Similarly, strong bases will have a higher percent ionization value. Percent ionization = OH | equilibrium Binitial Strong bases, for which K) is very large, ionize completely (100 %). For weak bases, the percent ionization changes with concentration. The more dilute the solution, the greater the percent ionization pH = Submit Part 8 What is the percent ionization of ammonia at this concentration? Express your answer with the appropriate units.
