The PH of 100% Bleach. The pH of 100% bleach is 11-13. This level of alkalinity is what makes it a corrosive cleaning product. Bleach has a powerful cleaning action and is widely used in both household and commercial settings. It can be diluted with water to reduce its alkalinity and make it less corrosive. The stability of bleach can be controlled to prevent the build-up of chlorate ion in the following ways: – Storage pH Liquid bleach stored in the pH 11 to 13 region is the most stable. – Dilution is an effective strategy for minimizing NaOCl decomposition. However, it is important that the pH be bleach is basically a solution of sodium HypoChlorite, or NaClO. This is a salt that contains the anion of the weak acid HClO, hypochlorous acid, and the cation of the strong base, NaOH. Because NaOH is a strong base, it fully dissociates into Na+ ions and OH- ions. However, the HClO is weak and does not fully dissociate. Hypochlorite concentration in household bleach varies by manufacturer. Many household bleach solutions contain 5.25% sodium hypochlorite, and a 1:10 dilution (5250 ppm Cl) will produce a 0.53% hypochlorite solution 1. Use of bleach solutions with lower hypochlorite concentrations will not provide the proper level of disinfection. The pH scale is a convenient way to represent the acidity or basicity of a solution. We can calculate the pH of a solution by taking the negative logarithm of the hydronium ion concentration, or pH = -log [H₃O⁺].
