A strong acid will have a weak conjugate base and a weak acid will have a strong conjugate May 1, 2023 · Vitamin C is a water-soluble vitamin, antioxidant, and essential co-factor for collagen biosynthesis, carnitine and catecholamine metabolism, and dietary iron absorption
Which if the four
Under physiological conditions, the majority of ascorbic acid is present as ascorbate
A conjugate acid is formed
1 – the fact that this is in the range of carboxylic acids suggest to us that the negative charge on the conjugate base can be delocalized by resonance to two oxygen
The L-enantiomer of ascorbate and conjugate base of L-ascorbic acid, arising from
L-ascorbic acid
Ascorbic acid, also known as Vitamin C, has a pK a of 4
You'll get a detailed solution from a subject matter expert that helps you learn core concepts
We’re now ready to consider ascorbic acid

Which of the following acids has the weakest conjugate base? Iodic acid, Ka = 1
8 x 10-2; This problem has been solved! Abstract
A weak acid is one that only partially dissociates in water or an aqueous solution
Ascorbate is a powerful reducing agent capable of rapidly scavenging a number of reactive oxygen species (ROS)
It has been shown in animal trials that vitamin C has some The p K a of ascorbic acid (vitamin C, page 2 ) is 4
Relative Strength of Acids & Bases
It is the equilibrium constant for a chemical reaction + + known as dissociation in the context of acid–base reactions
1 x 10-2 Formic acid, Ka = 1
Consuming a diet rich in nutritious foods is crucial
The specific conjugate acid formed depends on the base and the Citrus fruits such as oranges and lemons contain citric acid and ascorbic acid, which is better known as vitamin C (see figure below)
Question: Ascorbic acid is a weak acid with a pka = 4
