Ph value of dil hydrogen carbonate
WebThe lower the pH, the exponentially more Hydrogen. pH = -log[H +] We measure how acidic or basic (also called alkaline) substances are by using the pH scale. The pH scale goes from 0 to 14, and is relative to pure water, which has a perfectly neutral pH of 7. When the concentration of hydrogen ions goes up, the pH goes down (and vice versa). WebJan 23, 2024 · Properties of phenol as an acid With indicators The pH of a typical dilute solution of phenol in water is likely to be around 5 - 6 (depending on its concentration). That means that a very dilute solution isn't really acidic enough to turn litmus paper fully red. Litmus paper is blue at pH 8 and red at pH 5.
