A 0.185 M solution of a weak acid (HA) has a pH of 2.95. Calculate the acid ionization constant (Ka) for the acid.
fill in the chart below: 8. Fill in the chart below: | [OH-] T pH [H0] 7.37 x 10-5 M POH 4.61 x 10-3M 10.742 5.291
The formulas in the "Solution/PH" chart are different from the initial formulas which are confusing me. Can you help solve this?
The chart below has entries for several steps along the titration curve (which shows the pH as a function of the volume of NaOH solution added). To calculate the pH at each step, you must first understand what species are present and which chemical reactions are occurring, as that will dictate the method needed to calculate the pH. For each volume listed, Fill in the table with the major species (one or more) present in solution that could impact the...
