Title: What is the pH of a 2.23 M H2SO4 solution? Ka2 (H2SO4) = 1.2 * 10-2
Post by: keyag on February 16, 2024, 10:29:08 PM

Dear chemical forums, this assignment is due in 4 hours and I got 0.75/1 points making me think I got incorrect significant figures but I am pretty sure my answer is correct. I do not understand why I got deducted points. Please help me understand what I did wrong. Thank you in advance for your help.

Ka2 is given to 2 sig figs, isn't it?

Thanks for reply Borek. Unfortunately I did not get this problem in time, I am unsure. Thanks for help.
