Ph of 10-8 m hcl
WebbWhat is the pH of a 10^-8 molar HCL solution? pH = - log [H+] pH = - log 10^-8 = 8 But there is more to the story. Assuming an aqueous solution, we have to factor in the pH of neutral water which is 7, since [H+] is 10^-7, as a source of protons as well. Total proton molarity is 10^-7 + 10^-8 = 1.1 ×10^-7. pH = -log (1.1 ×10^-7) = 6.96 14 1 WebbFinal answer. Step 1/3. GIVEN, 1] Concentration of HCL solution = 2.7x10^-3 M. Dissociation of strong acid [HCL]:-. HCL ↽ − − ⇀ H A + + Cl A −. So, concentration of HCL is equal to concentration of H^+. Concentration of H^+ = 2.7x10^-3 M. NOW WE HAVE TO FIND OUT PH OF THIS GIVEN SOLUTION.
