What is the pH of a 2.5 molar solution of potassium hydroxide?
WebAug 30, 2015 · Since Ka is small compared with the initial concentration of the acid, you can approximate (0.20− x) with 0.20. This will give you Ka = x2 0.2 ⇒ x = √0.2 ⋅ 1.78 ⋅ 10−4 = 5.97 ⋅ 10−3 The concentration of the hydronium ions will thus be x = [H3O+] = 5.97 ⋅ 10−3M This means that the solution's pH will be pH sol = − log([H3O+]) WebTo determine pH, you can use this pH to H⁺ formula: pH = -log ( [H⁺]) Step by Step Solution to find pH of 0.15 M : Given that, H+ = 0.15 M Substitute the value into the formula pH = -log ( [0.15]) pH = 0.823909 ∴ pH = 0.823909 Its Acidic in Nature Similar pH Calculation Here are some examples of pH Calculation pH value of 0.17 M pH value of 0.19 M shared health research impact

WebThe unit for the concentration of hydrogen ions is moles per liter. To determine pH, you can use this pH to H⁺ formula: pH = -log ( [H⁺]) Step by Step Solution to find pH of 0.23 M : … WebMar 1, 2012 · 2 answers You looked up Kb which is right. You want Ka for CH3NH3^+ and they don't make tables for those. You ALWAYS know that KaKb=Kw; therefore, if you have Kb and want Ka it's Ka = Kw/Kb. If you have Ka and want Kb it's Kb = Kw/Ka. answered by DrBob222 March 1, 2012 Try equaling it (The Ka to the equation you found) to find the … WebThe pH of an aqueous solution of 7.05×10-2 M sodium nitrite, NaNO2 (aq), is .
