WebMar 16, 2024 · Here are the steps to calculate the pH of a solution: Let's assume that the concentration of hydrogen ions is equal to 0.0001 mol/L. Calculate pH by using the pH to H⁺ formula: \qquad \small\rm pH = -log (0.0001) = 4 pH = −log(0.0001) = 4 Now, you can also easily determine pOH and a concentration of hydroxide ions using the formulas: WebJan 30, 2024 · pH and pOH. Because the constant of water, K w is \(1.0 \times 10^{-14}\) (at 25° C), the \(pK_w\) is 14, the constant of water determines the range of the pH scale. To understand what the pK w is, it is important to understand first what the "p" means in pOH and pH. The addition of the "p" reflects the negative of the logarithm, \(-\log\). Therefore, …
