Ph of .25 m hcl
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 WebSince the pH scale is logarithmic, not linear, a solution of pH 1 would have ten times (not twice) the [H+] that a solution of pH 2. Likewise, a solution of pH 12 would be 10 times more alkaline than a solution of pH 11. pH Calculations Involving HCl Solutions 1. Given the Wt% of an HCl solution, what is its theoretical pH value?
