Webb11 dec. 2024 · As sodium hydroxide concentration increases, the hydrogen ion concentration decreases, and the pH of the solution increases . Drain cleaners and oven cleaners or concentrated lye sold at some hardware stores will typically have a pH from 13 to 14 — a highly alkaline pH. Webbalkaline condition maintained with sodium hydroxide (NaOH). In the synthesis of bir-nessites, different concentrations of silicon [molar ratio of Si/(Mn+Si): 0, 0.10, 0.25, ... and adjust the pH to be 3 or 6 with 0.1N HCl or 0.1N KOH. After the pH was adjusted, a pH 4 0.1M CrC13• 6H2O was added to the suspensions to yield 80 or 200ƒÊM of Cr
