Title: What is the percent ionization of this weak acid at this concentration? Post by: nvince on Apr 14, 2013 A 0.15m aqueous solution of a weak acid has a freezing point of -0.31 degrees C. What is the percent ionization of this weak acid at this concentration? The freezing point depression constant of water is 1.86 degrees C/m
Title: What is the percent ionization of this weak acid at this concentration? Post by: Smiler on Apr 14, 2013 0.31 = 1.86 x 0.15 x i
i = 1.11 1 x 100 / 1.11 = 90 % ionization = 100 - 90 = 10% |
