Which of the following is a characteristic of a base?
Choose all that apply
A. feels slippery
B. accepts protons
C. donates protons
D. tastes sour
A. feels slippery
B. accepts protons
The correct characteristics of a base are:
A. Feels slippery - This is a characteristic of bases, as they have a soapy or slick texture when touched.
B. Accepts protons - Bases are substances that can accept or receive protons (H+) during a chemical reaction.
D. Tastes sour - This characteristic is incorrect. Bases do not taste sour. In fact, sour taste is associated with acids.
To determine which of the characteristics is a characteristic of a base, let's analyze each option:
A. Feels slippery: This is a characteristic of bases. When bases are dissolved in water, they often feel slippery or soapy to the touch.
B. Accepts protons: This is also a characteristic of bases. Bases are called proton acceptors because they have the ability to accept or react with protons (H+ ions).
C. Donates protons: This characteristic is incorrect. Bases do not donate protons; instead, they accept protons.
D. Tastes sour: This characteristic is incorrect. Tasting sour is a characteristic of acids, not bases.
Therefore, the correct characteristics of a base are:
A. Feels slippery
B. Accepts protons
Hence, options A and B are the correct choices.
