V. LEARNING MATERIAL

Acid Base Theory based on Arrhenius

According to Arrhenius, acid is a substance that produce H+ ions in aqueous

solutions, while base is a substance that produce OH- ions in aqueous solutions.

Arrhenius acid base can be formulated as follows :

HxZ(aq) → xH+(aq) + Zx-

(aq) HxZ is acid

M(OH)x(aq) → Mx+(aq) + xOH-

(aq) M(OH)x is base

Acid Base Theory based on Bronsted Lowry

According to Bronsted Lowry, acid is a proton (H+) donor, while base is a proton

(H+) acceptor.

Conjugate Pairs of Acid and Base

An acid, after release one proton (H+), it will form a speci called conjugate base,

while a base, after accept one proton (H+), it will form a speci called conjugate acid.

Acid ↔ Conjugate base + H+

Base + H+ ↔ Conjugate acid

Acid Base Theory based on Lewis

Lewis give definition of acid and base based on the handover of electron pairs.

According to Lewis, acid is acceptor of electron pairs, while base is donor of electron

pairs.

VI. LEARNINGMODEL :

Learning model : Cooperative

Type : Think Pair Share (TPS)

Learning method : Lecture, Discussion, presentation and question and answer

VII. TOPIC : Acid Base Solution

SUBTOPIC : Acid Base Theory

VIII. LEARNING ACTIVITY

A. Introduction

Phase 1 : Present Goals and Set

Exploration

1. Teacher relate the topic by giving some question about acid and base

2. Teacher motivate the student by showing objects in daily life that have acid and bsa

properties

3. Teacher explain the learning objective by using power point media.

B. Main Activity

Phase 2 : Present Information

Elaboration

4. Teacher distribute worksheet to each student.

5. Teacher explain outline of the matter about acid base theory by using power point

media

6. Teacher inform to student that the learning model that will be used.

Think

7. Teacher ask the student doing worksheet that have been distribute independently

accurately.

8. Teacher walk around and observe student activities

Phase 3 : Organize Student Into Learning Team

Pair

9. Teacher divide the students into groups. Each student consist of two students (in

pairs).

Phase 4 : Assist teamwork and study

10. Teacher ask the student to discuss with member of each group about answer of

worksheet.

11. Teacher walk around and observe the activities of students in the group by

emphasize to student that responsibility, open minded and listen friend’s opinion,

and help friend that needed are required in the discussion process.

12. Teacher guide the students in the group who have difficulty.

Phase 5 : Test over materials

Share

13. Teacher ask the students to present the result of their discussion in front of the class

with their group and the other students to be good listener.

14. Teacher ask the student to respond the discussion result of group presentation. (respect other)

15. Teacher respond the ideas during the discussion. (giving opinion)

16. Teacher give opportunity to student to ask the material that has not been understood.

C. Closure

Phase 6 : Provide Recognition

Confirmation
