How hot is acid?

Answer 1

Stomach acid is not hot, it is the same (approximately 37oC) temperature that your body is naturally. It is a acid with a pH of about 1 to 3. This is about as acidic as common substances like lemon juice, soft drinks like colas, and vinegar. These levels of pH can dissolve the foods we eat, but due to the stomach's specialized structure (it has mucus secreting glands which protect its lining) it can hold and mix the foods without harm to itself.

Answer 2

Acid is usually at the same temperature as its surroundings. Acid does not burn you because it is hot, but because it causes chemical reactions with the skin. Many acids to release heat when they react, but temperatures usually will not rise above the boiling point of water.

Answer 3

The temperature of acid varies depending on the type and concentration. It is not typically measured in terms of temperature like a physical object, but rather by its pH level or corrosive strength. Some acids, like concentrated sulfuric acid, can generate heat upon contact with water or other materials due to exothermic reactions.
