A Hydrocloride Acid Solution Dialog

Teacher: Good morning students
Students: Good morning, Sir
Teacher: Well, can you guess. What this stuff I bring?
Students: No Sir, we don't know
Teacher: It's call hydrochloride acid solution
Students: Ooohhh
Teacher: Anybody know characteristic about hydrochloride acid solution from the way you see it?
Ei: I will
Teacher: Yes, please
Ei: It has a clear colour, si
Teacher: Yeah, that's right, anybody else?
Bi: Hydrochloride acid solution is one of strong acid
Teacher: Exactly
Ci: But Sir, why hydrochloride acid solution is strong acid?
Teacher: Nice question well, that's hydrochloride acid solution has mixed with two element. Which are hydrogen and chlorine have strong ion bond. So, that's can make a strong power to create a strong bond. Here, do you see the symbol?
Students: Yes Sir
Teacher: So anybody can analyze the meaning of this symbol?
Bi: Can I Sir?
Teacher: Yes, please
Bi: That's symbol has mean corrosive. The chemical material can distructive life tissue, and then can make iritationon the skin. We can feel itchy, because of that, even can makeour skin will peel
Teacher: Yeah! ecactly, what you say. Now we will ot prove that hydrochloride acid solution is corrosive. Do you guys bring ehat I command last week?
Ei: Sure Sir
Teacher: Bring it to me, please
Ei: Here you are
Teacher: Well, you guys can take a look what I will doing, so what will happen if I trying to drop the solution on this steroform?
Ci: Waahhh awesome. The steroform is melting!
Ei: It's amazing
Teacher: So you see it? It's melting right?. This experiment has prove one of the hydrochloride acid solution characteristic. So, what is the conclution about this experiment
Ci:I will
Teacher: Yes, please
Ci: So the conclution is hydrocloride acid solution is a strong acid. And it can separate in the water. Hydrochloride acid solution is made by covalent bond between hydrogen and chlorine. And it can make the steroform melt, Uh, I mean like it has corrosive characteristic
Teacher: Okay, that's right. I hope you learn more about this lesson. See you next week

English Resume: The Results of a Report from a Simple Chemical Experiment

pH Scale and Usage Indicator Theoretical basis The concept of acids and bases is based on several properties which are represented by a group of their aqueous compounds. Based on the properties shown, the acid is a compound that has a sour taste, and redacts the blue lacmus. Bases are compounds that have a bitter taste, and can brighten the red litmus. In aqueous solution, the acid produces H ⁺ and alkaline ions to produce OHˉ ions (Basic Chemical Practicum Guide, 2012: 56). The ion concentration [H ⁺ ] and the concentration of [OHˉ] in water, acid or base solution are very small numbers. Therefore, a chemist named Sorensen proposes a concept called PH (P means Potential and H is a symbol of the Hydrogen element) PH is defined mathematically as follows: PH = - Log [H ⁺ ] For PH in the environment: Ø   Acid: PH <7 Ø   Bases: PH> 7Neutral: PH = 7 (Tony Bird, 1987: 71) Acids and bases are chemicals that are present in everyday life.

English Resume: Cause and Effect Acid Rain in Chemistry

What is Acid Rain and What Causes It? “Acid rain” is a broad term used to describe several ways that acids fall out of the atmosphere. A more precise term is acid deposition, which has two parts: wet and dry. "Acid rain" is a popular term referring to the deposition of a mixture from wet (rain, snow, sleet, fog, cloudwater, and dew) and dry (acidifying particles and gases) acidic components.  Distilled water , once  carbon dioxide  is removed, has a neutral pH of 7. Liquids with a pH less than 7 are acidic, and those with a  pH  greater than 7 are alkaline. "Clean" or unpolluted rain has an acidic pH, but usually no lower than 5.7, because carbon dioxide and water in the air react together to form  carbonic acid , a weak acid according to the following reaction: H 2 O  (l) +  C O 2  (g) ⇌   H 2 C O 3  (aq) Carbonic acid then can ionize in water forming low concentrations of  hydronium  and  carbonate ...
