Question

What is the Bronsted-Lowry definition of an acid?

(A) a compound that donates protons
(B) a compound that accepts protons
(C) a substance that increases hydroxide ion concentration
(D)a substance that increases hydronium ion concentration

Answer 1

Bronsted-Lowry defines the compound which (A) donates protons as acid.

Step-by-step explanation:

According to this concept, an acid is a substance that donates hydrogen ion in a chemical reaction. Hydrogen ion is same as a proton as it has only one proton in its atom. According to him, a base is that substance that accepts hydrogen in a chemical reaction.

In a general sense, all proton donors are acids and all proton acceptors are bases. The higher the number of hydrogen ion donated, the more acidic the substance.

Answer 2

(A) a compound that donates protons .

Step-by-step explanation:

According to Bronsted-Lowry Model :

• Acids are proton donors.

• Bases are proton acceptors.

• So, the right choice is:

(A) a compound that donates protons .
