O. Chem Label each reactant and product of this reaction as a Bronsted acid or base. Label each reactant and product in this reaction as a Bronsted acid or base. Classify each of the following reactants and products as an acid or a base according to Bronsted’s theory CF3COOH + H2.0 H3O+ + CF3COO-
general orientation
Concepts and reason
Classify the given compounds or ions in the reactants and products as Bronsted acids or bases according to whether the group accepts the proton or donates the protons. Bronsted’s concept is based on proton transfer.
Fundamentals
Bronsted acid is defined as the species that donates a proton i.e. for other species and bronsted base is defined as the species that accepts the proton.
Step by step
Step 1 of 3
Write the given reaction as follows:
In the above reaction, the Bronsted acids are and . Bronsted’s bases are and .
Bronsted acid: and .
Bronsted Base: and .
In the given reversible reaction, it donates a proton to form and accepts a proton to form.
Likewise, the product side can accept a proton to form and can donate a proton to form.
So e are Bronsted acids and e are Bronsted bases.
Step 2 of 3
Write the given reaction as follows:
In the above reaction, the Bronsted acids are and . Bronsted’s bases are and .
Bronsted acid: and .
Bronsted Base: and .
In the given reversible reaction, it donates a proton to form and accepts a proton to form.
Likewise, the product side can accept a proton to form and can donate a proton to form.
Step 3 of 3
Write the given compounds as shown below:
and
The Bronsted acids are and .
Bronsted’s home port is .
Consider the reaction of the given compounds with water and observe if they accept a proton from water or donate a proton to water as shown below:
As it donates a proton i.e. an ion to water and forms, so it acts as a Bronsted acid.
As it contains a negative charge, so it accepts a proton, i.e. a water ion, so it acts as a Bronsted base.
As it donates a proton, i.e. an ion to water, so it acts as a Bronsted acid.
Answer
Bronsted acid: and .
