WebApr 3, 2024 · Complete answer: As we know that HCl is a strong acid, so its pH will be less than 7. The concentration of HCl = 10 − 8 M Total [ H +] = [ H +] obtained from HCL + [ H +] obtained from H 2 O [ H +] HCl being a strong acid, it completely ionizes. [ H +] H C l … WebThe HCl is a strong acid and is 100% ionized in water. ion concentration is 0.0025 M. Thus: pH = - log (0.0025) = - ( - 2.60) = 2.60 Top Calculating the Hydronium Ion Concentration from pH The hydronium ion concentration can be found from the pH by the reverse of the mathematical operation employed to find the pH. [H3O+] = 10-pH or [H3O+]
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?
