Example English Dialogue about Chemistry
"Corrosive"
Teacher : Good Afternoon Class
Students : Good Afternoon ma'am
Teacher : Well, Can you guess what the stuff I bring?
Students : No ma'am, We don't know
Teacher : It's call hydrocloric acid solution
Students : Ohh
Teacher : Does anybody know the characteristic about hydrocloric acid solution from the way you see it?
Amel : I know
Teacher : Yes please
Amel : It has clear color ma'am
Teacher : exactly, anybody else? yes please
Rika : hydrocloric acid solution is a strong acid ma'am
Teacher : That's right!
Oni : But ma'am, why hydrocloric acid solution it strong acid?
Teacher : Nice question! well that's because hydrocloric acid solution has mixed by 2 elements, which is hydrogen and cl have strong ion bond, so that's can make a strong power to create a strong bond. Here do you see this symbol?
Students : Yes, we are
Teacher : So anybody can analyze the meaning of this symbol?
Rika : Can I ma'am?
Teacher : Yes please
Rika : That's symbol has mean corrosive. the chemical material can destructive life tissue, and then can make irritation on the skin. we can feel itchy because of that and our skin will peel
Teacher : Yeah! that's exactly what you say. Now we will to prove that hydrocloric acid solution is corrosive. Do you guys bring what I command last week?
Student : Yes ma'am
Teacher : Bring it here please
Amel : 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 the steroform?
Oni : Woahh awasome... the steroform is melting
Amel : It's Amazing
Teacher : So you see it? it's melting right? this experiment has prove one of the hydrocloric acid solution characteristic, so what is the conclusion about this experiment?
Oni : So the conclusion is hydrocloric acid solution is a strong acid, and it can separate in the water, hydrocloric acid solution is made by covalent bond between H and Cl . And it can make the steroform melt, uhh I mean like it has corrosive characteristic
Teacher : Yeah that's right. that is the conclusion about hydrocloric acid solution, okay I think it's enough, I hope you learn more about this lesson, see you next week.

Can you explain to me that HCl is corrosive?
BalasHapusWell, the chemical material in HCl can destructive life tissue, and then can make irritation on the skin. we can feel itchy because of that and our skin will peel, that is the characteristic of corrosive in HCl
HapusCan you put down the gold in hydro cloride acid solution?
BalasHapusYa, there is a few way to Cultivate gold. one of that way is Process by HCl-Cl method.
HapusZelvy,
BalasHapusName an example of a hydrochloric acid solution ?
With major production starting in the Industrial revolution, hydrochloric acid is used in the chemical industry as a chemical reagent in the production of large-scale vinyl chloride for PVC plastic, and MDI / TDI for polyurethane. This acid has many smaller-scale applications, including household cleaners, gelatin production and other food additives, anti-crust (descaling), and skin processing.
