Question

Which of these is a property of bases? question 2 options:

O they taste bitter.
O they feel sticky.
O they produce hydrogen gas when reacted with metals.
O they taste sour.

Answer 1

Bases are known to have a bitter taste and feel slippery to the touch; they do not typically react with metals to produce hydrogen gas but do change the color of indicators such as litmus and phenolphthalein.

Step-by-step explanation:

One of the properties of bases is that they often have a bitter taste and are found in foods less frequently than acids. Unlike acids which have a sour taste and react with metals to produce hydrogen gas, bases do not typically react with metals in this manner. In addition to the taste, many bases, such as soaps, feel slippery to the touch. Bases also change the color of indicators; for instance, litmus turns blue in the presence of a base, while phenolphthalein turns pink. These properties help to easily distinguish bases from acids in chemistry.

The property of bases is that they turn litmus paper blue and have a bitter taste if ingested. Bases are also slippery to the touch, like soaps. However, they do not react with metals to produce hydrogen gas like acids do, and they do not taste sour.
