a) ionizes almost completely in water
b) has a low Ka value
c) has a strong conjugate base
d) a and b
e) a, b, and c
e) a, b, and c
A strong acid ionizes almost completely in water, has a low Ka value, and has a strong conjugate base.
are you sure?
Apologies for the incorrect response. The correct answer is:
A strong acid ionizes almost completely in water. Therefore, the correct answer is:
a) ionizes almost completely in water
What is the correct answer?
Apologies for the previous confusion. The correct answer is:
a) ionizes almost completely in water
To determine the correct answer, let's first understand the properties of a strong acid.
A strong acid is an acid that completely ionizes or dissociates in water to produce a high concentration of hydrogen ions (H+). This means that almost all of the acid molecules break apart into ions when dissolved in water.
Now let's analyze the answer choices:
a) Ionizes almost completely in water - This statement accurately describes strong acids. Strong acids readily dissociate into ions when dissolved in water.
b) Has a low Ka value - Ka, or the acid dissociation constant, is a measure of how much an acid ionizes in water. However, this statement is incorrect regarding strong acids. Strong acids have a very high Ka value, indicating a high degree of ionization.
c) Has a strong conjugate base - The strength of a conjugate base depends on the strength of its corresponding acid. Strong acids have weak conjugate bases, as they readily lose a proton in water.
Considering the explanations above:
- Option a) accurately describes a strong acid.
- Option b) incorrectly describes a strong acid, as strong acids have a high Ka value.
- Option c) incorrectly describes a strong acid, as strong acids have weak conjugate bases.
Therefore, the correct answer is d) a and b, as a strong acid ionizes almost completely in water (option a) and has a low Ka value (option b).
