pH as a Measure of Acid and Base Properties
WebApr 27, 2015 · Like you guessed, the pH should be around 7, since the concentration of HCl is very low. Obviously, it can't be 11.65, since it's still an acid. The reason for this discrepancy is that, for low concentrations, you must consider the self-ionization of water in order to get the correct concentration of H X 3 O X + ions. Consider the equilibrium: WebCalculate the pH for a solution of HCl with an (H3O)+ of 1 X 10-6 M. Expert Answer. Who are the experts? ... Step 1/1. HCl is a strong acid that completely dissociates in water, producing H+ ions. Therefore, the (H3O)+ concentration in a solution of HCl with a given concentration can be found by simply taking the negative logarithm of the HCl ... how good is hulu service
