WebJul 30, 2016 · Determine the pH of the solution by taking the negative logarithm (-log) of the concentration of H 3O+ ions. pH = −log(1.0 × 10−6) = 6 Then obtain the pOH using the equation: pH +pOH = 14. Rearrange to solve for pOH: pOH = 14 − 6 = 8 WebJan 6, 2024 · The base is a substance that produces OH-ions in solution. If hydrogen ions H + outnumber hydroxide ions OH-, the solution is acidic. The pH scale ranges from 0 to 14. …

WebThe Brønsted-Lowry definition: Brønsted argued that all acid-base reactions involve the transfer of an H + ion, or proton. Water reacts with itself, for example, by transferring an H + ion from one molecule to another to form an H 3 O + ion and an OH - ion. According to this theory, an acid is a "proton donor" and a base is a "proton acceptor ... something\u0027s got to give marilyn monroe
