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
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
