Acid Base Equilibria
Please show all work and remember this is a first year course. Chem is my weakest subject.
Please send responsse in Word.
Also, if you are not willing to show me the proper way to do these by showing the calculations and will only supply me with some notes tht I could read out of any textbook myself, please do not take this posting and my money as others have.
1. Determining Ka. What is the Ka value for a weak acid if a 0.0150-M solution has a pH of 2.67?
2. Calculations With Ka. What is the pH of a 0.250-M benzoic acid solution? Ka = 6.3 * 10^-5
3. Polyprotic Weak Acid. What are pH, [H3O+], [HSO3-], and [SO32-] in a 1.50 M sulfurous acid solution?
4. Calculations With Kb. What is the Kb value for a weak base if a 0.250-M solution has a pOH of 4.7?
5. The pH of a Salt Solution. What is the pH of 0.50-M sodium benzoate? The benzoate ion (C7H5O2-) is the anion of benzoic acid.
All questions answered with proper expanations. Answer as a Word attachment.

- Difference between a weak acid and a strong acid - What is the difference between a weak acid and a strong acid? Cite an example of each.
- Calculate the pH of a weak acid (acetic acid) - Given the Ka value of acetic acid is 1.8e-5, find the pH of a 0.25M acetic acid solution. Also find its Kb value.
- Calculate [H+], [HA] and [H2A] for a weak dibasic acid - Calculate [H+], [HA] and [H2A] for a 0.1M solution of the weak dibasic acid H2A. Given: H2A=H+ + HA- Ka1=2.0 X 10-5 HA- = H+ + HA- Ka2=1.00 X 10-12
