What is a chemical property of vinegar?

A) the pH of vinegar is around 2.4

B) vinegar freezes at around 2 degrees Celsius

C) vinegar boils at about 100 degrees Celsius

D) the color of vinegar ranges from colorless to brown

E) vinegar is transparent liquid

The physical and chemical properties of vinegar include

chemical formula, density, boiling and freezing points and pH. ... The chemical formula of vinegar is one of its basic chemical properties. Chemical formula refers to the chemical composition of acetic acid since vinegar is essentially a dilute solution of this acid.

answer : (a) volume of the gas = 8.67 ×   l

                (b) second virial coefficient b = -1.21226 l/mole

solution :   given,     t = 300k

                                p = 20atm

                                z = 0.86

                                n = 8.2 mmoles = 8.2 × moles

                                r =   0.082 l atm/k/mol

        find,     (a) volume of gas   and (b) second virial coefficient b at 300k.

formula used :            

                          and            

(a)            

                    = \times 0.082\times 300}{20}[/tex]

                    = 8.67 ×   l

(b)      

                    = (0.00867-1) × 8.659

                    = - 8.5839 l/mole
