Phenolat pkb
WebJan 28, 2024 · Since pK a + pK b = 14, the higher the pKa the stronger the base, in contrast to the usual inverse relationship of pK a with acidity. Recall that ammonia (NH 3) acts as a base because the nitrogen atom has a lone pair of electrons that can accept a proton. WebUse table search to locate desired compound in database. Unless otherwise stated, pKa and pKb was measured at STP. For reference or additional information, please contact [email protected]
