Popular questions
Consider an aqueous solution which is .20m in potassium propanoate?
It will be basic, since propionate is the conjugate base of propionic acid (pKa ≈ 4.87); a 0.20 m aqueous solution has a pH of about 9.1.
Potassium propionate and aluminum powder make what?
They do not form a special or energetic compound under normal conditions—mixing them typically yields just a physical mixture with no reaction.
What is the decimal value for the hexadecimal number e283?
57987.
What is the fraction of association (α) for the following potassium propionate solutions?
In water, potassium propionate is essentially fully dissociated, so the fraction of association is ~0 (the degree of dissociation is ~1 at typical concentrations).
Is citric acid bad for you?
At typical food levels, citric acid (E330) is considered safe by major regulators (GRAS; EFSA/JECFA). Concentrated or frequent acidic exposure can irritate the mouth/stomach or contribute to tooth enamel erosion.
Where does the citric acid cycle occur?
In eukaryotic cells it occurs in the mitochondrial matrix; in bacteria it occurs in the cytosol.
What does citric acid do to your body?
It is a normal intermediate in energy metabolism and is readily metabolized to carbon dioxide and water. Citrate can bind minerals, which may enhance absorption of some and help prevent certain kidney stones by increasing urinary citrate.
Where does citric acid come from?
It occurs naturally in citrus fruits, but most food-grade citric acid is produced by fermenting sugars (e.g., from corn, beet, or cane) with Aspergillus niger.
How is citric acid made?
Industrially, sugars are fermented with Aspergillus niger to produce citric acid, then it is recovered and purified—often by precipitating calcium citrate and converting it back with sulfuric acid or via ion-exchange/crystallization.
