Which of the following is considered acidic? (1 point)
Ammonia
O Soap
O Vinegar
O Lime Water
Vinegar
The substance that is considered acidic among the listed options is vinegar.
To determine which of the given options is considered acidic, we can look at their pH values. pH is a measure of how acidic or basic a substance is, with values less than 7 being acidic. Here's an explanation of how to find the answer:
1. Ammonia: To determine the acidity of ammonia, you can refer to its pH value. However, ammonia is actually a base, not an acid. Its pH value is typically above 7, making it alkaline or basic. Therefore, ammonia is not considered acidic.
2. Soap: Soap is also not considered acidic. Soap is generally neutral or slightly basic. It typically has a pH value close to 7 or slightly above, making it less acidic and more on the basic side.
3. Vinegar: Vinegar, on the other hand, is considered acidic. It contains acetic acid, which gives it a low pH value. Typically, vinegar has a pH value around 2-3, indicating its acidic nature.
4. Lime Water: Lime water is mainly composed of calcium hydroxide, which is a strong base. Therefore, lime water is not acidic but rather basic.
Therefore, out of the given options, vinegar is considered acidic.
