WebbSolution for Calculate the pH for a 4.3 × 10−8 M HCl solution with an ionic strength of m = 0.1. yH+ = 0.83, yOH− = 0.76 and yCl− = 0.755. Webb8 apr. 2013 · 1 Answer Sorted by: 7 For (a), the Henderson-Hasselbalch equation, p H = p K a + log ( [ A X −] / [ H A]), comes in handy. Because your molarities and volumes of the acid and its conjugate base are equal, this indeed reduces to simply p H = − log ( 6.3 ⋅ 10 − 5).
What is the pH of the solution if the Ka of HClO= 2.8 * 10 8 2. What …
WebbSodium hypochlorite, commonly known in a dilute solution as (chlorine) bleach, is an inorganic chemical compound with the formula NaOCl (or NaClO), [3] comprising a sodium cation ( Na+. ) and a hypochlorite anion ( OCl−. or ClO−. ). It may also be viewed as the sodium salt of hypochlorous acid. Webb16 mars 2024 · Here are the steps to calculate the pH of a solution: Let's assume that the concentration of hydrogen ions is equal to 0.0001 mol/L. Calculate pH by using the pH to H⁺ formula: \qquad \small\rm pH = -log (0.0001) = 4 pH = −log(0.0001) = 4 Now, you can … The reaction quotient (Q) is a function of the concentrations or pressures of the … The formula developed by Dr. Henderson described the use of carbonic acid as a … The solution is here!
