Question

which is a chemical property of vinegar?
a. the ph of vinegar is around 2.4.
b. vinegar freezes at around 2°c.
c. vinegar boils at about 100°c.
d. the color of vinegar ranges from colorless to brown.
e. vinegar is a transparent liquid.

Explanation:

To determine the chemical property of vinegar, we distinguish between chemical and physical properties. Chemical properties involve reactions or interactions (like acidity, determined by pH, which relates to how vinegar reacts with other substances). Physical properties (freezing/boiling points, color, transparency) describe appearance or state changes without altering the substance’s chemical identity. Option A (pH ≈ 2.4) reflects vinegar’s acidic nature (a chemical property), while B–E are physical properties.

Answer:

A. The pH of vinegar is around 2.4.
