WebFeb 24, 2024 · The pH scale ranges from 0 to 14 under usual conditions and measures the acidity of an aqueous solution. This is derived from the molarity of protons (hydrogen ions, or H+) in the solution. ... Thus 6 mol of NaCl in 8 L of aqueous solution has a molarity of 6 mol/8 L = 0.75; 6 mol of the much more massive molecule adenosine triphosphate ... WebAt 25 0 C, summation of pH and pOH is 14. We use that relationship to determine pH value. pH + pOH = 14 pH + 2.88 = 14 pOH = 11.12 When ammonia solution is diluted by ten times, it's pH value is reduced by 0.5. As an example, 0.1 mol dm -3 ammonia solution is diluted to 0.01 mol dm -3, pH value is reduced from 11.13 to 10.63. Questions
WebDie Lösung einer starken Säure mit einer Konzentration von 1 M (1 mol/L) hat einen pH-Wert von 0. Die Lösung eines starken Alkalis mit einer Konzentration von 1 M (1 mol/L) hat einen pH-Wert von 14. Das bedeutet, das für die meisten entstandenen Probleme der pH-Wert hauptsächlich im Bereich von 0 bis 14 liegt.
