Problem: Calculate the pH of the following solutions (work must be shown). Include the balanced equation for the acid dissociation reaction0.10 M HOCl (Ka = 3.5x10-8)

FREE Expert Solution

We are asked to calculate the pH of 0.10 M HOCl (Ka = 3.5x10-8) solution.


Since HOCl has a low Ka value, it’s a weak acid. 

Remember that weak acids partially dissociate in water and that acids donate H+ to the base (water in this case). 


The dissociation of HA is as follows:

HOCl(aq) + H2O(l)  H3O+(aq) + OCl(aq); Ka = 3.5x10-8
