Which of the following is a product formed from a base reacting with HCl? A) Structural isomer, B) octahedral crystal, C) sulfur dioxide, D) chloride salt, or E) amorphous.

HCl is an acid. When an acid reacts with a base, that’s called a neutralisation reaction. The products of that are salt and water. In this question, we want the product that’s formed as a result of this reaction. Water isn’t an answer choice. So the answer we’re looking for must be a type of salt.

Since the acid that we’re working with in this question is hydrochloric acid, when it reacts with a base, such as sodium hydroxide, for example, it’s going to form a chloride salt, such as sodium chloride. So the product that’s formed from a base reacting with hydrochloric acid is a chloride salt, which is answer choice D. But let’s take a look at our other answer choices so we know what they are.

Structural isomers are molecules with the same molecular formula. But the atoms are connected in a different order. For example, the molecule on the left is called butane. The molecule on the right is called 2-methyl propane. Both of these have the molecular formula C4H10 because they both have four carbons and 10 hydrogens. But these molecules are arranged differently. So they’re structural isomers.

Our next answer choice is octahedral crystal, which is a type of crystal that’s formed when we have six atoms or molecules bonded to a central metal atom. For example, manganese(II) oxide forms an octahedral crystal.

The next answer choice is sulfur dioxide, or SO₂, which is a corrosive gas that’s predominantly produced from burning fossil fuels.

Our final answer choice is amorphous, which is a type of solid that has a varied structure. We can compare a crystalline solid to an amorphous solid. In a crystalline solid, the atoms are arranged in an ordered and repeating way, like fruit that is neatly stacked in a display. In an amorphous solid, on the other hand, there is no order or repeating structure. An example of a crystalline solid is the chloride salt that we talked about earlier. An example of an amorphous solid would be glass.

But of our answer choices, the one that is a product that’s formed from a base reacting with HCl is a chloride salt.
