Question

An acid that dissociates to the extent of 92% in water would be termed a strong acid.

True or Fasle?

Answer 1

The given statement," An acid that dissociates to the extent of 92% in water would be termed a strong acid." is false.

Step-by-step explanation:

In chemistry, the degree to which an acid dissociates in water classifies it as either strong or weak. An acid that dissociates 100% into ions when dissolved in water is deemed a strong acid. In contrast, acids that do not reach 100% dissociation are termed weak acids. An example of a weak acid is acetic acid (CH3COOH), which has a dissociation level significantly lower than 100% when dissolved in water.

Considering the given information, an acid that dissociates to the extent of 92% in water would not meet the criteria for a strong acid, as it does not fully dissociate. Thus, even with a high dissociation percentage such as 92%, this acid would still be classified as a weak acid. It is important to note that in practical terms a 92% dissociation indicates a relatively strong acid amongst weak acids, but it is not categorized as a strong acid in the technical sense.

Answer 2

Answer: False

Step-by-step explanation:

Strong acid is defined as the acid which completely dissociates when dissolved in water. They have low pH. These releases ions in their aqueous states.

`HNO_3(aq.)\rightarrow H^+(aq.)+NO_3^-(aq.)`

Weak acid is defined as the acid which does not completely dissociates when dissolved in water. They have high pH. These releases ions in their aqueous states.

`CH_3COOH\rightleftharpoons CH_3COO^-+H^+`

Thus as the given acid is only 92% dissociated and cannot be completely dissociated, it is termed as a weak acid.
