From this salt the benzoate ion C6H5-COO- is a base ( the other part Na+ is neutral).
This base has a pKB value of 9.80 (benzoate)
The pKacid value of its conjugated benzoic acid ( C6H5-COOH) however is
pKbenzoic-acid = 4.20 = pKa
(which is (not surprisingly) equal to 14.0-pKbase = 14.0-9.80)
p-hydroxybenzoic acid (pKa=4.48)
The PKA of benzyne is 43.
35
15,7
The conjugate acid is Hydrogen (H2), the pKa of which is 35.
Sodium Benzoate (NaC6H5CO2)
Very Polar
Yes: potassium benzoate, calcium benzoate, sodium, potassium and calcium sorbates, sorbic and benzoic acids and many others (Food additives, E200-E290).
Yes, Benzoic acid is a weak acid (pKa ~ 4.2) that will dissolve in weak base such as sodium bicarbonate (pKa ~ 6.4)
Sodium benzoate is a non toxic compound.
sodium benzoate glutin free
15,95 mg of sodium in 100 mg sodium benzoate
Sodium benzoate has the formula C6H5COO-Na+
These substances are very different.
Yes. Sodium benzoate is a compound and thus a pure substance.
As the chemical formula for sodium benzoate is:NaC6H5CO2The answer appears to be yes.
Sodium benzoate made of Sodium, Carbon, Hydrogen, and Oxygen the equation ( NaOH + C7H6O2= NaC6H5CO2 + H2O)
1.sodium benzoate
Another common name doesn't exist; the code of sodium benzoate is E211.
NO!!! They are two different chemicals. Sodium hydroxide is NaOH Sodium benzoate is ( C6H5)COO^-Na^+. It is the salt of benzoic acid.
