Answer to Question #128625 in General Chemistry for Zach Strohmeyer

Question

What is the Bronsted-Lowry definition of acids and bases? Identify the acid, base, conjugate acid, and conjugate base in the following reactions:



a. H2O + HF ↔ F - + H3O+



b. PH3 + H2O ↔ PH4+ + OH-



c. HCO3- + OH- ↔ H2O + CO32-

Answer 1

According to Bronsted-Lowry an acid is a H+ ion donor while as a base is H+ ion acceptor

a) Acid - HF

Base- H₂O

Conjugate A- F^-

Conjugate B- H₃O+

b) Acid - H₂O

Base- PH₃

Conjugate A- PH₄

Conjugate B- OH^-

c) Acid -HCO₃

Base-OH^-

Conjugate A-H₂O

Conjugate B-CO₃^2-
