Are two solutions, 1.0 M HCI and 1.0 M CH3COOH, equally strong?
No, they are not equally strong.
HCl is a strong acid, which means it completely ionizes in water, releasing a high concentration of hydrogen ions (H+). In a 1.0 M solution of HCl, you would have a high concentration of H+ ions, making it highly acidic with a very low pH.
CH3COOH, on the other hand, is a weak acid. It only partially ionizes in water, so it releases a much lower concentration of H+ ions compared to HCl. In a 1.0 M solution of CH3COOH, you would have a lower concentration of H+ ions, making it less acidic with a higher pH compared to HCl.
