The concept of pH was first introduced by the Danish chemist Søren Peter Lauritz Sørensen at the Carlsberg Laboratory in 1909 and was revised to the modern pH in 1924 to accommodate definitions and measurements in terms of electrochemical cells. In the first papers, the notation had H as a subscript to the lowercase p, thus: pH•. For the sign p, I propose the name 'hydrogen ion exponent' and the symbol pH•. Then, for the h… WebSo we have the pH and our goal is to solve for the concentration of hydronium ions, and pH is equal to the negative log of the concentration of hydronium ions. So we can plug our pH right into this equation. So that would give us the pH which is 9.25 is equal to the negative log of the concentration of hydronium ions.

It's definitely possible to increase the concentration of H+ to beyond 1.0 mol dm-3, and pH will become negative. Similarly, we … WebWhen you are given the molarity of an acid solution, and asked to determine the pH, a molarity greater than 1 produces a negative pH. Is this possible? It's possible. If the molarity of hydrogen ions is greater than 1, you'll have a negative value of pH. For example, you might expect a 12 M HCl solution to have a pH of -log (12) = -1.08. ms アカウント ローカルアカウント 切り替え
