A strong acid __________.
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).
