How to Calculate Hydroxide ion (OH-) Concentration from pH

Web30 mrt. 2024 · pOH is the negative logarithm of hydroxide ion concentration [OH–]. pOH = -log10 [OH–]. The greater the concentration of OH – ions present in an aqueous solution, the lower its pOH (< 7). However, it has a high pH value (> 7) which denotes that the given solution is strongly basic in nature. WebIt is used to determine the basicity of the solution. pOH is equivalent to the negative logarithm of hydroxide ion concentration. pOH = – log [OH –] If the pOH value is less than 7, the solution is basic. If the pOH value is equivalent to 7, the solution is neutral. If the pOH value is more than 7, the solution is acidic. pOH Formula ... comedyclub toomler amsterdamWebPick one of the formulas: in this case, we are finding pOH and pH is known, so the formula is: pOH + pH=14 Plug in the information into the formula: pOH + 0.699 =14 Enter and look on the graphing calculator for the answer: pOH= 13.3 drunk dora the explorer

"WebTo calculate the pH of an aqueous solution you need to know the concentrationof the hydronium ion in moles per liter (molarity). The pH is then calculated using the expression: pH = - log [H3O+].
