Which of the following cannot describe sulfuric acid? (A) It has the chemical formula H2SO4. (B) It has a bitter taste. (C) It turns a blue litmus paper red. (D) It is a strong acid. (E) It has a corrosive effect on the skin.

The name sulfuric acid tells us that this compound is an acid. An acid is a substance that dissociates in water to produce positively charged hydrogen ions. There are many different substances that can be classified as an acid, and each of these substances share similar characteristics. Acids tend to have a sour taste. Lemons, vinegar, and Coca-Cola all contain acids. We can test for the presence of an acid using blue litmus paper, as acids will turn a blue litmus paper red.

Now that we’ve looked at acids in general, let’s look more specifically at sulfuric acid. Sulfuric acid has the chemical formula H2SO4. Acids range from weak to strong with sulfuric acid being considered a strong acid. In general, the stronger the acid, the more dangerous the acid is. Strong acids like sulfuric acid tend to be corrosive. This means that the acid has high reactivity that can cause damage to other materials and bodily tissue.

Now that we know some more about sulfuric acid, we can determine which of the statements cannot describe it. We know that sulfuric acid has the chemical formula H2SO4. It is a strong acid, and it is corrosive. So answer choices (A), (D), and (E) can describe sulfuric acid and therefore cannot be the answer to this question. Sulfuric acid, like all acids, will turn a blue litmus paper red. So answer choice (C) cannot be the answer to this question. This leaves us with answer choice (B). We know that acids have a sour taste, not a bitter taste. The type of compound that typically has a bitter taste is a base. Therefore, the statement that cannot describe sulfuric acid is answer choice (B): it has a bitter taste.
