Answer :
In the context of taste, bitterness is often associated with bases. Bases are substances that have a pH greater than 7 and can accept protons (H+ ions) in a chemical reaction. When a base comes into contact with taste buds on the tongue, it can elicit a bitter taste sensation.
Examples of substances that are bases and can have a bitter taste include:
1. Baking soda (sodium bicarbonate) - commonly used in baking and cleaning, has a bitter taste.
2. Ammonia - a common household cleaner, has a strong and bitter taste.
3. Magnesium hydroxide - an ingredient in antacids, has a slightly bitter taste.
Therefore, in the given options, the substance most likely to have a bitter taste is definitely a base.
