Consider the following statements and choose the incorrect option.
Answer: D
The incorrect statement is acetic and formic acids are the most common acids in apple.
The main acid in apples is malic acid (the name comes from malum, Latin for apple). Acetic acid is the acid of vinegar, and formic acid is found in ant stings and nettles.
The other statements are accepted. Baking soda (sodium bicarbonate) releases carbon dioxide and is used in dry-chemical and soda-acid fire extinguishers. Tooth enamel is made of calcium phosphate (hydroxyapatite), a basic compound, which is why acids erode it. Ascorbic acid (vitamin C) treats scurvy.
