Question

______ Scientist gave definition of acid-base on basis of chemical properties.

• A. Arrahenius
• B. Boyle
• C. Bronsted-Lowry
• D. Lewis

Answer 1

The correct option is C Bronsted-Lowry

The Scientists Johannes Nicolaus Bronsted and Thomas Martin Lowry independently developed definitions of acids and bases based on the compounds' abilities to either donate or accept protons ($H^{+}$ ions). In this theory, acids are defined as proton donors; whereas bases are defined as proton acceptors.

Thus, option C is correct.
