How to figure out ph from molarity
Web1. The first thing to do would be to see which equation fits in best with the question asked. Here we are looking for [H+] so the best equation would [H+]= 2nd log (-pH) since we already have the value of pH. 2. The next step would be to plug in the given information to the equation. Here we have pH so we would plug 3 into the equation for pH. Web24 de dic. de 2024 · Using the Concentration to Calculate pH 1 Remember the pH equation.
