Ask your question and … WebHere, we are going to calculate pH of 0.1 mol dm-3 aqueous ammonia solution. Dissociation constant (K b) of ammonia is 1.8 * 10-5 mol dm-3. Following steps are important in calculation of pH of ammonia solution. First, pOH is found and next, pH is found as steps in the calculations. See the below example.
WebTo calculate the pH you can use the equation: pH= -log[H3O+]. In case of HCl (very strong acid) you can assume that it is 100% ionised in H2O. Therefore, pH= -log (molarity). WebMar 6, 2024 · pH is an expression of hydrogen ion concentration in water. Specifically, pH is the negative logarithm of hydrogen ion (H +) concentration (mol/L) in an aqueous solution: pH = -log 10 (H +) The term …
