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 … WebbIn such cases [H+]total would be calculated as follows. [H+]total = [H+]acid+[H+]water = 10−8+10−7 Since[H+] in water is10−7 molL−1 at 25∘ C = 10−7(0.1+1) = 1.1×10−7 pH = …

WebbAt pH below 2, the majority of the chlorine in the solution is in the form of dissolved elemental Cl 2. At pH greater than 7.4, the majority is in the form of hypochlorite ClO −. The equilibrium can be shifted by adding acids (such as hydrochloric acid) or bases (such as sodium hydroxide) to the solution: ClO − (aq) + 2 HCl (aq) → Cl 2 (g ...

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 … Webb10 apr. 2024 · The correct answer is 6.98. Concept: The degree of acidity or alkalinity is a measurement of the hydrogen ion concentration in a solution is known as pH. Calculation: Concentration of HCl = 10 −8 M [H +] total = [H +] acid + [H +] water Since, HCl is a strong acid, it completely ionises. [H +] HCl = 1.0×10 −8 WebbStudy with Quizlet and memorize flashcards containing terms like pH, Acids, ... What is the molar concentration of OH- in pure water? 1x10^-7 Students also viewed.
