WebCalculate the hydrogen ion concentration of a solution that is 1.0 M in acetic acd and 0.20 M in sodium acetate. Solution. If we let x equal the moles of acetic acid that ionize, the concentration at equilibrium will be: x = hydrogen ion concentration. 1.0 -x = acetic acid concentration. 0.20 - x = acetate ion concentration http://www.chem.uiuc.edu/rogers/Text12/Tx126/tx126.html
WebMay 20, 2024 · To get the log value on your calculator, enter the number (in this case, the hydronium ion concentration) first, then press the LOG key. If the number is 1.0 x 10 -5 (for [H 3 O +] = 1.0 x 10 -5 M) you should get an answer of "-5". If you get a different answer, or an error, try pressing the LOG key before you enter the number.
