Click For Summary

Homework Help Overview

The discussion revolves around identifying Lewis acids and bases, as well as determining the formulas for their conjugate bases. The original poster seeks clarification on specific conjugate bases and the identification criteria for Lewis acids and bases.

Discussion Character

  • Conceptual clarification, Assumption checking

Approaches and Questions Raised

  • Participants explore the definitions of Lewis acids and bases, with some attempting to clarify the relationship between acids, bases, and their conjugates. Questions about specific conjugate base formulas are raised, alongside discussions on the nature of electron donation and acceptance.

Discussion Status

The discussion includes various interpretations of Lewis acid-base theory, with some participants providing definitions and examples. There is an ongoing exploration of the concepts without a clear consensus on the original poster's questions regarding specific conjugate bases.

Contextual Notes

Participants reference external resources and previous knowledge, indicating a mix of understanding and assumptions about the definitions and relationships in acid-base chemistry.

Whats the formula for this conjugate bases? how do I get them?

a) HSO3tothe(-)
b) NH3
c) HCL

and how is the lewis acid and lewis base identified?

thanks

Read J.D.Lee, elementary questions, pal.
Viloating the Rules I guess, but I will answer.
So Acid are something with donatable H+, which means accepting e-!
That is exactly Lewis Acid, anything that accepts e- is an Acid.
Anything that donates e- is Base!

That is all...

Lewis ACID: Any compound in need of electrons.
Lewis BASE: Any compound that can donate electrons.

Conjugate Concept:
------------------

Suppose you need the conjugate acid of NH3 (Ammonia) which is a base, NH4+ , by gain of electron.

Also A STRONG ACID HAS A WEAK CONJUGATE BASE AND A STRONG BASE HAS A WEAK CONJUGATE ACID.
 
lewis acid/bases interact through dative bonding (the lewis base donates both of the electrons thus it will be the one with the lone pair).
