WebMar 15, 2024 · Acids have pH values of less than 7 and bases have pH values of greater than 7, because pH is a measure of the concentration of hydrogen ions in a solution. Smaller values mean a higher hydrogen ... WebNov 20, 2013 · p H + p N H X 2 = − log k a m ≃ 33 ( − 50 ∘ C) ( ( a m) stands for a substance solvated by ammonia). Hence, in liquid ammonia at − 50 ∘ C, the pH scale can easily go all the way from 0 to 33 (of course, it can go a little lower and higher still, but again now activities become important), and that neutral pH is actually 16.5.
