Web2 days ago · Here, the concentration of H3O+ is equal to the concentration of HCl. pH + pOH = 14. For measuring pH, we adopt different methods depending on the concentration of … WebHCl is a strong acid that will be full ionized in solution. HCl → H+ + Cl-So, the concentration of [H+] = 0.25 M (or 0.25 mol/L). The equation that relates pH and [H+] is. pH = -log[H+] so the pH of the 0.25 M HCl solution will be. pH = -log (0.25) = 0.6
WebThe pH of a solution ranges from 1-14, 1-6 are acidic, 7 is neutral, and 8-14 are basic. It is a measure of the amount of hydrogen ion concentration in a solution and any change greater than 0.5 can cause loss of function or death to any organism. WebJan 3, 2024 · HCl is a strong acid, and it dissociates completely. HCl(aq) → H+(aq) + Cl−(aq) Therefore, the molarity of HCl, or [HCl], is pretty much the same as [H+]. ⇒ [H+] = 0.1 M. It really doesn't matter what the volume is. pH depends on the concentration, not the mols. pH = −log[H+] = − log(0.1) = 1. Answer link.
WebA pH electrode is used to obtain the data that are plotted in the titration curve shown above. (a) Identify the solution that was initially added to the beaker. Explain your reasoning. The solution in the beaker was the 0.100 M HCl because the initial pH was 1 (the pH of 0.100 M HCl). One point is earned for the correct identification with ...
