b) Formic acid
e) Tartaric acid
d) Hydrochloric acid
organic acid?​

Answer 1

Answer:

a) Lactic acid, b)Formic acid and e)Tartaric acid are all organic acids.

While d) Hydrochloric acid is a mineral acid.

Explanation:

Organic acid is a type of organic compound hat has typical acidic properties.

• Organic acids are weak acids and do not totally dissolve in water.
• Organic acids are less reactive to mineral acids.
• Lactic acid has the formula $C_{3} H_{6} O_{3}$. It is found in pickled and fermented food. It is organic acid.
• Formic acid has the formula $CH_{2} O_{2}$. It is found as venom in bee and ant stings. It is organic acid.
• Tartaric acid has the formula $C_{4} H_{6} O_{6}$. It is found in plants, specifically tamarinds and grapes. It is organic acid.

Mineral acids are acid derived from inorganic compound. These are highly soluble in water but tend to be insoluble in organic solvents.

• Hydrochloric acid (HCl) is a mineral acid. It is a strong acid. It has many uses in cleaning, pickling, refining, electroplating etc. It is a colorless watery liquid with sharp odor.
