Is capric acid the same as decanoic acid?
Capric acid, also known as decanoic acid or decylic acid, is a saturated fatty acid. Its formula is CH3(CH2)8COOH.
What is the percent composition of decanoic acid?
Decanoic acid, natural, >=98%, FCC, FG.
What is the main intermolecular forces of decanoic acid?
Answer: Decanoic acid has one more methylene group than nonanoic acid, so it has stronger van der Waals attractive forces than nonanoic acid and a higher boiling point. Explain why the boiling point of 2,2-dimethylpropanoic acid (164 °C) is lower than that of pentanoic acid (186 °C).
Is decanoic acid soluble or insoluble in?
Decanoic acid is soluble in a NaOH solution. Decanoic acid has a long hydrocarbon chain that is nonpolar, so it is insoluble in water.
What is decanoic acid soluble in?
Decanoic acid (sodium salt) is soluble in organic solvents such as ethanol, DMSO, and dimethyl formamide (DMF). The solubility of decanoic acid (sodium salt) in ethanol is approximately 30 mg/ml and approximately 5 mg/ml in DMSO and DMF.

Decanoic acid/Formula
How many carbon atoms are in decanoic acid?
A straight-chain, twelve-carbon medium-chain saturated fatty acid with strong bactericidal properties; the main fatty acid in coconut oil and palm kernel oil.
Which is pKa indicates the weakest acid?
A small Ka value means little of the acid dissociates, so you have a weak acid. The Ka value for most weak acids ranges from 10 -2 to 10 -14 . The pKa gives the same information, just in a different way. The smaller the value of pKa, the stronger the acid. Weak acids have a pKa ranging from 2-14 .
What are the pKa values of carbonic acid?
The p Ka of carbonic acid was found to be 3.49 ± 0.05 using both the Marcus and Kiefer-Hynes free energy correlations. This establishes H 2 CO 3 as being 0.37 p Ka units stronger and about 1 p Ka unit weaker, respectively, than the physiologically important lactic and pyruvic acids.
What is the pKa value of acetic acid?
Acetic acid’s density is 1.053 g/mol at room temperature in the liquid form, though it can also exist as a solid. The pKa of acetic acid is 4.76, which is the pH value at which half of the acid will be intact and the other half in the ionic form. The formula for the acetate ion (the conjugate base of acetic acid) is CH 3 COO–.
What is the pKa of the acid?
The pKa of an acid is a constant associated with how much the acid ionizes in solution. pKa is a combination of the p in pH, which stands for power of hydrogen, and the dissociation constant for acids, represented by Ka. Since strong acids, by definition, ionize completely, pKa is more important as a characteristic of weak acids.
