WebCitrate(3-) is a tricarboxylic acid trianion, obtained by deprotonation of the three carboxy groups of citric acid. It has a role as a fundamental metabolite. It is a citrate anion and a tricarboxylic acid trianion. It is a conjugate base of a citrate(2-). … WebThe equilibrium concentration of hydronium ions is equal to 1.9 times 10 to negative third Molar. So we plug that in. And the initial concentration of our weak acid, which was acidic acid is 0.20 Molar. So the Molars cancel, and we get a percent ionization of 0.95%. A low value for the percent ionization makes sense because acidic acid is a ...
WebASK AN EXPERT. Science Chemistry 16 The odor of fish is due primarily to amines, especially methylamine (CH3NH₂). Fish is often served with a wedge of lemon, which contains citric acid. The methylamine reacts with the citric acid to form an odorless product, methylammonium citrate, thereby making less-than- fresh fish more appetizing. WebOct 27, 2011 · Best Answer. Copy.

WebOrange juice, which generally has a pH around 3.5, is acidic because it contains citric acid. Citric acid is a weak acid which means that it does not completely dissociate in water. The behavior of weak acids can be described by an equilibrium constant, Ka. Usually Ka is reported as pKa, where pKa = -log(Ka). The pKa for citric acid is 3.13.
