ALINEAL
SEASON 2 - ALEA: Chapter 33
As promised, Rangga accompanied his daughter and friends to study at his residence for OSN preparation.
"Well, Nindy called me earlier. He said for the next three days he could not teach because he was in Surabaya" Alea said.
"It's okay, there's Dad. Dad already asked Uncle Edgar to reduce Dad's schedule, so you don't have to worry" Rangga smiled towards his daughter who was sitting in line with his friends.
"Gue wants Lea, every day studying at your house, as long as you teach us" whispered one of Alea's friends.
"What the hell loe!!" Alea glanced resentfully at her friend "He is mine" he said with a sharp look.
"Okay, now the material is the calculation of Acid Base Titration" Rangga wrote it on the board.
"Before entering the formula there are two types of Acid Base Titration?" ask Rangga.
"Alkalimetry Titration and Acidimetry Titration" Alea answered quickly.
"Good"
"Remember the formula Ma x Va x na \= Mb x Vb x nb" said Rangga "Ma: acid concentration, Mb: base concentration, na : acid valence amount, nb : the number of base valences, Va: acid volume, and Vb: base volume" Rangga explained.
"We go directly to the question on page 141 No. 2" Rangga paused for a moment to give the children the opportunity to read the matter "There are those who want to try to answer" Rangga thrust the marker he held.
"I" Tistan raised his hand and then he moved from his seat to Rangga.
While carrying the package book to see the problem Tristan forward.
"Be aware of the contents of the table, the titration of a solution of CH3COOH with a solution of Ba(OH)2 0.1 M" said Rangga.
Tristan began writing formulas, then entering the numbers into formulas and counting them.
"Good Tristan" praised Rangga, he invited Tristan to sit back.
"So that's the calculation, anyone want to ask?" ask Rangga.
The children shook their heads to understand the material conveyed by Rangga.
Amidst her excitement teaching Alea and her friends, Ana comes with a drink and food for her grandchildren and friends.
"For you" Ana gave a glass of mango juice to Rangga.
"Thank you Mother"
'Son, if you were still around, you would see your husband as an amazing father' Ana murmured.
"Together, Mother entered again yes want to prepare dinner for you" Ana passed leaving Rangga and Alea with her friends who were studying.
Rangga resumed his material, they all studied until 20:30 pm, of course with several breaks for dinner and prayer. All her daughter's friends who come to her house, are obliged to follow all the rules in the Rangga house, especially on time prayers for Muslims.
Alea and Rangga drove Alea's friends to the terrace of his house, some were picked up by his parents and some were taken by the driver to their respective homes, Rangga tried to take responsibility for his daughter's friends who came to his house.
"Don't you see if Tristan is so smart and handsome? it seems like he likes you" Rangga teased his daughter.
"What the hell Well, I don't want to think about it. I want to focus on OSN and class up so that my grades are good and can be accepted to study in Germany like Dad"
"She wants to take medicine?"
"Yes but in Germany yes Well"
"By, I'll be with you"
"really?"
"Of course, honey, I'll always keep you company until Dad's job is done"
"I mean Dad?"
"Until you get married later, yes we have a break tomorrow you have to go to school" Rangga gave a sweet kiss on the forehead of his daughter "Good night"
"Dad Good Night, love you"
"Love you too honey" Rangga turned off his daughter's room lights and then he came out of Alea's room to his study, he smiled when he saw the project cooperation with Mr. Setiadjie began on the run.
