LESSON PLAN

School : Senior High School

Subject : Chemistry

Class/Semester : XII/I

Main Material : Equalization Method of Equation Redox Reaction

Meeting : I

Method : lecture and discussion

Time Allocation : 2 x 45 minutes

I. COMPETENCES STANDARD

Understanding basic concept of equalization of equation redox reaction.

II. BASIC COMPETENCES

Students able to equalization of equation redox reaction

III. Topics

1. Redox reaction (reduction-oxidation) is electron transfer reaction

2. An atom that accept electron is called reduction

3. An atom that release electron is called oxidation

4. The method to balancing the redox reaction equation is 2 kinds, those are:

· Oxidation state : amount of electron that release by redactor same with

the amount of electron that accept by oxidator

· Ion electron : redox reaction is separated become a half reduction

reaction and a half oxidation reaction

IV. INDICATORS

1. Student can explain the meaning of redox reaction

2. Student can explain the meaning of reduction

3. Studrnt can explain the meaning of oxidation

4. Student can explain the equalization method of equation redox reaction

5. Student can equalization of equation redox reaction

V. Step of Learning Activity:
