Carboxyl
The carboxyl group. Carboxyl acts as an acid by contributing an H plus to a solution.
carboxalic group
It is a solid. See the discussion page for further info. (It does not matter that it is dispersed, it still maintains its fundamental state of matter.) Citric acid (anhydrous) is a solid at temperatures below 153C (307F). Citric acid becomes liquid at 153C. At some temperature well above that, pure citric acid may enter vapor phase, but its likely the energetic state of atoms in the molecule at this temperature will cause it to come apart. The boiling point of a solution of citric acid in water depends on the concentration of citric acid in the water.
Citric acid in milk products is only an additive from other sources; it is not a natural product of fermentation.
The question is not quite clear. If it is meant to mean "Does citric acid cause vomiting?" The answer would usually be no. Citric acid is the acid found in citrus fruit, such as oranges and lemons. The acidity would not cause vomiting, as the stomach uses hydrochloric acid to digest food, and is able to cope with quite strong concentrations. The citric acid could cause vomiting if too much was consumed at once, but even water can cause vomiting if taken in very large quantities.

carboxalic group
Polarity occurs when there are un-bonded electrons within the molecule. Without the alcohol functional group, the cholesterol molecule would be non-polar. However, since there is an alcohol functional group, the oxygen's extra electrons cause this molecule to be polar. This alcohol functional group allows the possiblility of linking with other molecules using an ester or hydroxyl bond.
One cause of acidic ground water is polluted rain water, which can be acidic.

You should never cook fruits in an unlined copper pan because if it is an acidic fruit it can react with the copper and can cause poisoning. Copper is a reactive metal. Similarly, it is not wise to store foods in copper pans.
