Review | constants | periodic table percent ionization can be used to quantify the extent of ionization of an acid in solution and is defined by the following formula for the acid ha: percent ionization=[ha] ionized[ha] initial×100% percent ionization increases with increasing ka. strong acids, for which ka is very large, ionize completely (100%). for weak acids, the percent ionization changes with concentration. the more diluted the acid is, the greater percent ionization. a convenient way to keep track of changing concentrations is through what is often called an i. c.e table, where i stands for "initial concentration," c stands for "change," and e stands for "equilibrium concentration." to create such a table, write the concentrations of reactant(s) and product(s) across the top, creating the columns, and write the rows i. c.e on the left-hand side. such a table is shown below for the reaction: a+b⇌ab initial (m)change (m)equilibrium (m)[a] [b][ab]
a certain weak acid, ha, has a ka value of 1.0×10−7.
part a.) calculate the percent ionization of ha in a 0.10 m solution.
part b.) calculate the percent ionization of ha in a 0.010 m solution.
