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 … WebVariation of pH and H+ ion concentration Aqueous acetic acid solution has the pH value of 3 and concentration of acetic acid is 0.05 mol dm-3. What is the H + concentration of acetic acid solution? Because pH value is given, we can find the H + concentration directly from pH equation. pH = -log[H +] 3 = -log[H +] [H +] = 1 * 10-3 mol dm-3
WebSo the negative log of 5.6 times 10 to the negative 10. Is going to give us a pKa value of 9.25 when we round. So pKa is equal to 9.25. So we're gonna plug that into our Henderson-Hasselbalch equation right here. So the pH of our buffer solution is equal to 9.25 plus the log of the concentration of A minus, our base. WebThe pH of an aqueous solution is based on the pH scale which typically ranges from 0 to 14 in water (although as discussed below this is not an a formal rule). A pH of 7 is considered to be neutral. A pH of less than 7 is considered acidic. A pH of greater than 7 is then …
