Dialogue : Reaction
kinetics and discoloration of trafic light
Ayu: hi al,
Al: hai ayu,
Ayu: what are you doing?
Al: i'm doing a trial on the reaction kinetics and the color change of the solution
Ayu: how to do it?
Al: 1. Put 50 ml of solution into the measuring flask
2. added 5 - 10 ml indicator
3. tutu the gourd
Ayu: wooow ... the solution is yellow .
Al: then shaken slowly, what happened?
Ayu: yellow color turns red
Al: well last, shake loudly, what happened?
Ayu: when shaken loudly, it turns green to color. Why color change occurs when given different actions? Can you explain.
Al: so the change occurs because the indicator is reduced with alkaline and produces a yellow color, when slowly shaken oxygen oxidation and produces a red color, when shaken violently again turns green due to the continued oxidation of the solution.
Ayu: ooo ... so the color change is affected by several factors:
1. indicators
2. redox reaction
3. oxygen
4. Oxidation
Al: yes, right.
Ayu: thanks for the explanation.
When we start with an effect and ask why it occurred, we find a cause; but if we ask why again, what was just now a cause becomes an effect. An example of this is shown in the table below listing a column of effects and a column of causes (read left to right, top to bottom). This relationship continues as long as we continue to ask why.
cause : the reason something happen
effect :what happen
cause & effect : explain why things happen.
We can divide the most common linking words and
expressions of cause & effect into four
group:
1. Coordinating Conjunctions: for (cause), so (effect)
2. Subordinating Conjunctions: because, since, if, whenever, so that, as (cause)
3. Conjunctive Adverbs: therefore, for this reason, as a result, thus, that is why,
consequently (effect)
4. Preposition: because
of, reasons for, consequences of, due to (cause)
