How are pH and pOH related? A. pOH = 14 - Brainly
Web3 de ago. de 2024 · In this case, we must remember that pH and pOH are referred to a measure of acidity and basicity respectively, since pH accounts for the concentration of H⁺ and pOH for the concentration of OH⁻ in a solution. In such a way, since the maximum scale is 14, we say that the addition between the pH and pOH must be 14: WebThe p H of pure water is 7 , the negative logarithm of 1 X 10 - 7 . A neutral solution is one that is neither acidic nor basic . The hydrogen ion concentration equals the hydroxide ion concentration , and both equal 1 X 10 - 7 M. In a neutral solution , then , pH = pOH = 7 . Question 4: Acids and Bases (5 points) 1. Web9 de abr. de 2015 · The equation is pKw=pH+pOH. pKw is always equal to 14! pH and pOH are related because they are both just math treatments! Both of them equal Kw.
