Vinegar contains acetic acid and turns blue litmus to red.

Answer:

Vinegar turns litmus paper into (a) red.

Explanation:

• Vinegar is a combination of acetic acid and water prepared by double fermentation process.

• Vinegar is acidic in nature. The pH value of the white distilled vinegar is around 2.5. The acetic acid content in it makes it acidic.

• Litmus paper is used for determining the nature of any solution, either acidic or alkaline.

• If solution is acidic, blue litmus paper turns into red.

• If a solution is basic or alkaline, red litmus paper turns into blue.

• A neutral litmus paper is purple in color.
