Topic:Acids and bases
From Wikiversity
Welcome to the Wikiversity Department of Acids and Bases, part of The School of Chemistry.

[edit] Department description
The Department of Acids and Bases is a Wikiversity content development project where Wikiversity participants can create, organize and develop learning resources for the fundamental topic of acid/base chemistry.
The acid and base concepts can be explained by two different ways.
1. Lewis Acids/Base 2. Bronsted Acids/Base
Lewis Acids/Bases :
Lewis acid is an electrophile, which can accept a pair of electrons from a coordinate covalent bond to fullfill its octet configuartion. The other extreme belongs to the class of lewis base.
Eg of lewis acids : BF3, AlCl3 ..etc Eg of lewis bases : NH3 etc..
Bronsted Acids/Bases :
In simple terms, this can be defined as the tendancy of an atom to release or to accept a proton (H+). Thus, proton donors are considered as Brosnted acids (eg, HCl, H2SO4 ..) and then the proton acceptors are termed as Bronsted bases (eg, OH-, CH3COO-). In general solution chemistry often the acidity refers to the Bronsted acidity. The further advancements in this concepts leads to more common pKa, pKb, pH etc terms.
The "topic" namespace contains pages that are for management and organization of small academic units at Wikiversity such as departments (see: Wikiversity:Topics).

- 9 December 2006 - Department founded!
[edit] Learning Projects
See: Learning Projects and the Wikiversity:Learning model.
Learning materials and learning projects are located in the main Wikiversity namespace. Simply make a link to the name of the learning project (learning projects are independent pages in the main namespace) and start writing! We suggest the use of the learning project template (use "subst:Learning project boilerplate" on the new page, inside the double curved brackets {{}}).
Learning materials and learning projects can be used by multiple departments. Cooperate with other departments that use the same learning resource.
Remember, Wikiversity has adopted the "learning by doing" model for education. Lessons should center on learning activities for Wikiversity participants. We learn by doing.
Select a descriptive name for each learning project.
