The ph of a solution at 25 c which has twice
Webb9 juli 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 … WebbTo do that will use its Moeller Mass. Then, once we have the moles of sodium hydroxide, we need to divide by the leaders of Solution, we have 400 mil leaders, which we can convert toe leaders. Then we will have moles of sodium hydroxide over leaders of Solution, which will give us arm Olara T of 4000.5 Moeller sodium hydroxide..
