Question

does the term acid by default means that it contains a little water?​

Answer 1

Answer:

In pure water, there are an equal number of hydrogen ions and hydroxide ions. The solution is neither acidic or basic. An acid is a substance that donates hydrogen ions. An acid is any hydrogen-containing substance that is capable of donating a proton (hydrogen ion) to another substance. A base is a molecule or ion able to accept a hydrogen ion from an acid. Acidic substances are usually identified by their sour taste.
