WebJul 20, 2024 · Find the pH of (a) 0.1 M HOCl (hypochlorous acid) and (b) 0.1 M NaOCl (sodium hypochlorite) from the value for Ka given in the table of Ka values. Solution a) For 0.1 M HOCl, we find in the usual way that [H3O +] = √Kaca = √3.1 × 10 − 8 mol L − 1 × 0.1 mol2 L − 2 = 5.57 × 10 − 5 mol L − 1 so that pH = 4.25 WebThe dissociation constant of an acid HA is 1×10 −5 the pH of 0.1 molar solution is: Ionization constant K b for NH 4OH is 1.8×10 −5.

WebA solution consisting of 0.1 M CH3NH3Cl and 0.1 M CH3NH2 would be a more effective buffer than one containing 1.5 M CH3NH3Cl and 1.5 M CH3NH2 If [CH3NH3+] = [CH3NH2], then pH = 7.00. False: If HCl were added to the initial buffer solution, then the [CH3NH3+] would decrease. False: If [CH3NH3+] < [CH3NH2], then the [H+] is larger than the Ka value.
