Popular questions
Is potassium sorbate bad for you?
Generally no; potassium sorbate (E202) is a low-toxicity preservative approved by major regulators, though high concentrations can irritate and rare sensitivities occur.
Is potassium sorbate safe?
Yes—it's considered safe at permitted food levels by authorities like FDA, EFSA, and JECFA; occasional mild sensitivities have been reported.
How much potassium sorbate per gallon of mead?
Typically about 0.6–1.0 g per US gallon (≈150–250 mg/L) to inhibit refermentation; add after fermentation is complete and alongside sulfite.
How much potassium sorbate per gallon of wine?
Commonly about 0.6–1.0 g per US gallon (≈150–250 mg/L); use with sulfite and check any local limits on sorbate levels.
Is potassium sorbate gluten free?
Yes—it's a synthetic preservative and contains no gluten, so it's suitable for people with celiac disease.
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).
