WebJul 21, 2024 · The pKa value of an acid is a quantitative measurement of a molecule’s acidity. The pKa is derived from the equilibrium constant for the acid’s dissociation reaction, Ka, and uses a logarithmic scale to allow the pKa values to span wide ranges. pKa = –log Ka The lower the pKa value of an acid, the stronger the acid. WebAnswers (1) Ethyne (Acytylene) is less acidic than water or ethanol. So it reacts with very strong Bases. C2H2 reacts with sodium amide in liquid ammonia and forms sodium acetylide.
