    E.   Description of Learning Materials

Acid–Base Reactions: Neutralization Reactions

When a strong acid and a strong base solution are mixed, a neutralization reaction occurs, and the products do not have characteristics of either acids or bases. Instead, a neutral salt and water are formed. Look at the reaction below:

HCl_(aq) + NaOH_(aq) H₂O_(l) + NaCl_(aq)

The anion from the acid (Cl^–) reacts with the cation from the base (Na⁺) to give a salt, and a salt is defined as any compound formed whose anion came from an acid and whose cation came from a base.

    F.    Learning Methods

a.       Learning approach            : the concept and process approach

b.      Learning model                 : STAD

c.       Methods                            : The method of discussion and information

   G.  Learning Activities

Activity	Phase	Teacher Activities	Student activities	Allocation of Time
Introduction	Orientation	Teacher is conditioning student to focus and introducing about Titration Acid- Base	Student Concentrate and ready to study	10 minute
	Apersepstion	Teacher ask to student about matery acid-base in last meeting	Student answer the question that teacher given
	Motivation	Teachers arouse  students' curiosity by telling me  about  how Sodium chloride can beformed from two  different compounds are  concentrated HCl  and NaOH compound	Student curious and pay attention
	Giving Reference	Teacher explain about learning objective and source of learning relevant	Student listen the teacher explanation
	Division of group learn	Teacher divide student in 5 group	Student start to sit on its group
Core	Explanation	Teacher give the subject matter about Acid Base Titration and Neutralization Reaction	Student attention it	65 minute
	Eksploration	The teacher asks the students to start talking about the Acid Base Titration and Neutralization Reaction that they have earned Teacher give students the freedom to seek the source materials from anywhere Teacher enable student to using learning media like virtual lab	Students start to disscuss in each groups and  seek the material about the Acid Base Titration and Neutralization Reaction
	Elaboration	Teacher ask one group for presentating result of its discussion about the Acid Base Titration and Neutralization Reaction Teacher ask to the other group to answer to result of from group which is presentation	Student presenting result of its discussion Student from other group answered
	Confirmation	Teacher explain about matery that have learned and clarify mistake in discussion	Student give attention clarification of teacher
	Evaluation	Teacher ask student to doing  simple question from book about the Acid Base Titration and Neutralization Reaction that have been learned individually Teacher ask one of member from the group to present one of the answer of question that determined by teacher in front of class	Student to do it
Cover	Achievement	Teacher give assessment to each group which is presentating result of its discussion Teachers also give a personal assessment to any student who asks and respond to discussions of other groups	Student pay attention Student conclude matery which have been studied	15minute
	Reflection	Teachers guide students and concluded the subject matter The teacher gives the students the task to be done at home  The teacher asks the students to re-learn the material that has been taught	Students pay attention

2.      Assessment Tools

  1.    0.3 M HCl solution is titrated with NaOH solution, the titration end point is reached when10 ml of HCl solution requires 75 ml of NaOH solution. Determine the molarity of NaOH?

  2.    Determine the concentration of 20 ml of Ca (OH) 2 is titrated with 100 ml of 0.1 M HCl solution!

Key Answer

Determine the concentration of 20 ml of Ca (OH) 2 is titrated with 100 ml of 0.1 M HCl solution!
1. Given: MA = 0.3 M 

VB = 75 ml         VA = 10 ml 

nB = 1    nA = 1
Asked: MB?
Answer:                              
                              MB = 0.04 M

         2.      Given: VA = 100 ml    VB =  20 ml
            MA = 0.1 M 

nB = 2 nA = 1
Asked: MB?
Answer: VA x MA x nA = VB x MB x nB
               100 x 0.1 x 1 = 20 x MB x 2
                MB = 0.25 M
