D. tastes sour
The correct answer is:
C. donates protons
D. tastes sour
To determine which of the following is a characteristic of an acid, you need to understand the properties and behavior of acids.
A. "Feels slippery" is not a characteristic of an acid. It is a characteristic of bases, which have a soapy or slippery texture when they come into contact with the skin.
B. "Accepts protons" is not a characteristic of an acid. Acids, in fact, donate protons.
C. "Donates protons" is indeed a characteristic of an acid. Acids are substances that can release hydrogen ions (H+) or donate protons in a chemical reaction.
D. "Tastes sour" is another characteristic of an acid. Some acids, such as citric acid in citrus fruits and acetic acid in vinegar, have a sour taste.
Therefore, the correct answers are C. donates protons and D. tastes sour.
