The ph of 10-8 m of hcl in water is
WebbThis is a solution of HCl. The solution is acidic. The ph must therefore be less than 7.00If you take HCl to dissociate completely , then [H+] = 8*10^-8MIf you apply the formula:pH … WebbMass of HCl = 11.8 mol; Because HCl amount is found in 1 dm 3 solution, that HCl amount become the concentration of HCl. Therefore, concentration of HCl is 11.8 mol dm-3. pH …

WebbThe pH of an aqueous solution is based on the pH scale which typically ranges from 0 to 14 in water (although as discussed below this is not an a formal rule). A pH of 7 is considered to be neutral. A pH of less than 7 is considered acidic. WebbWhat is the pH of 8×10−8 M HCl? pH = Expert Answer 1st step All steps Final 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
WebbPure water has a pH of 7 at 25°C, meaning it is neutral. When an acid is dissolved in water, the pH will be less ... For example, a 5×10 −8 M solution of HCl would have a pH of 6.89 when treated as a mixture of HCl and water. The self-ionization equilibrium of solutions of sodium hydroxide at higher concentrations must also be ...
Webb19 juni 2024 · Table 7.14. 1: Some of the common strong acids and bases are listed here. For a strong acid, [ H +] = [ A −] = concentration of acid if the concentration is much higher than 1 × 10 − 7 M. However, for a very dilute strong acid solution with concentration less than 1 × 10 − 7 M, the pH is dominated by the autoionization of water. flower delivery wenatchee waWebbOn using this relation, p H = – l o g [H 3 O +], we get pH equal to 8.
