Question

According to ____________, Base is a proton acceptor.
1 point
A. Arrhenius concept
B. Bronsted Lowry concept
C. Lewis concept
D. None of the above​

Answer 1

Answer:

option b

Explanation:

In the Bronsted-Lowry definition of acids and bases, an acid is a proton (H⁺) donor, and a base is a proton acceptor. When a Bronsted-Lowry acid loses a proton, a conjugate base is formed

Answer 2

Answer:

Strong or concentrated bases have a caustic effect on organic substances and have a violent reaction with acids. Aqueous solutions or molten bases split into ions and carry electricity. Under normal circumstances, a basic solution's pH value is always higher than 7.

Explanation:

A base, according to Arrhenius, is a substance that raises the concentration of the hydroxide ion ($OH^{-}$) in an aqueous solution.

According to the Brosted-Lowry concept, proton acceptors are Bronsted bases. A Bronsted base can only "accept" a proton by providing an electron pair and forming a bond with it. As a result, Bronsted bases frequently consist of compounds containing unshared pairs of electrons that can be transferred to a proton in order to establish a bond i.e., a covalent bond.

According to Lewis's concept, an electron-pair donor is a Lewis base. It is a substance where a pair of electrons is donated to form a covalent bond.

Thus, according to Bronsted Lowry's concept, Base is a proton acceptor.

Hence, the correct option is (B) the Bronsted Lowry concept.
