WebThe pH scale is logarithmic and shows the solution’s concentration of hydrogen ions inversely. More specifically, the pH of the solution is the negative logarithm to the base 10 of its hydrogen ion concentration in moles per litre. The pH scale can be traced to a series of standard solutions whose pH is defined by international agreement. WebApr 8, 2024 · 1 Answer. You are most likely getting an inaccurate value. As anticipated in Poutnik's comment above is difficult to reliably measure a p H of very acidic solution but the p H scale is indeed open, and negative p H are a real thing. It is easy and more meaningful to state a very high concentration or activity rather than reporting inaccurate p H. react three fiber scroll animation
