Final answer:

Acids react with active metals, c) limestone, have a b) sour taste, and change d) blue litmus paper to red, but they do not characteristically react with grease and oil.

Step-by-step explanation:

The properties of acids include the ability to change the colour of blue litmus paper to red, react with active metals to release hydrogen gas, and exhibit a sour taste as found in substances like lemons and vinegar. They also react with substances like limestone (calcium carbonate) to release carbon dioxide. However, the property that acids do not have is the ability to react with grease and oil. Grease and oil are not typically water-soluble, and while some acids can emulsify fats to some extent, this is not a defining characteristic of acids, especially in comparison to bases, which are known for their ability to saponify, or react with, fats and oils.
