Find ph using concentration
WebJul 9, 2014 · To calculate the pH of HCl you need to know the concentration expressed in molarity (mol HCl/L solution). You will use the following equation to find the pH. pH = -log[H+] This means you take the negative log of the hydrogen ion concentration to find the pH. The hydrogen ion concentration is the same as the concentration of the acid … WebMay 25, 2024 · Calculating pH using H+ or H3O+ concentration

WebMar 6, 2014 · The molarity becomes the [H+] concentration of 3.2 × 10−3. We know this is the [H+] concentration because HNO3 is a strong acid, since the acid will completely dissociate into H+ and NO− 3. To find the pH calculate −log[H+] −log[3.2 × 10−3] = 2.49 = pH. To find the pOH take the pH value and subtract it from 14. 14 −2.49 = 11.51 = pOH.
WebFeb 24, 2024 · To go from molarity to pH, use your calculator or a similar tool to take the logarithm to the base 10 (the default base) of the molarity, reverse the sign to get a positive value, and you're done!
