e. 1, 2 and 3

Explanation:

1. Acids are indeed proton donors. This is based on the Brønsted-Lowry acid theory which defines an acid as a substance that can donate a proton (H+ ion) to another substance.

2. Acids do react with bases to produce a salt and water. This is known as a neutralization reaction.

3. Many acids do have a sour taste. This is a characteristic of food items like lemons and vinegar, which contain citric acid and acetic acid respectively. However, it's important to note that not all substances with a sour taste are safe to eat or drink, and tasting should not be used as a method to identify acids in a lab setting.
