模块8的概述:应用化学想法

在第8个模块中:应用化学思想,您将了解如何在我们的日常生活中识别和量化有机物质和无机物质。

这对于确保某种化学物质在安全浓度范围内,最终管理合成产品带来的健康和环境风险非常重要!

Inquiry Question 1: How are the ions present in the environment identified and measured?

Ever since junior science, we recognise Chemistry by the vibrant colours of test tube solutions.

In Year 12, we will be using these colours to identify inorganic cations and anions through two different methods, the flame test and precipitation test.

看起来是时候修改来自模块6的降水规则:该主题的酸/碱反应!

A good tip is to记住识别特定阳离子或阴离子的火焰或沉淀物的颜色!

除了识别cations and anions, we will also be calculating the concentration of these ions through colorimetry, ultraviolet-visible spectrophotometry and atomic absorption spectroscopy!

呼,声音像一把!

但是同样,我们不需要知道这些过程背后的复杂工程。不过,了解每个过程背后的原理很有用。

For example, atomic absorption spectroscopy (AAS) takes advantage of the fact that each ion has their own unique absorbance (extent of absorbing light) in order to quantify its presence in a sample.

Now it’s your turn to ask yourself, which feature of the ion is being exploited in this process?

Inquiry Question 2: How is information about the reactivity and structure of organic compounds obtained?

After we’ve mastered identifying and measuring无机离子, it’s time to face its more difficult twin,ORGANIC compounds.

有机化合物,例如烯烃,醇和羧酸可以通过其反应性来鉴定。It’s important that you understand how these compounds react with others and what the reaction produces.

Here is a table summarising the organic compound, the reaction used to identify them and the product it results in.

有机化合物 Reaction Product
Alkenes
加法反应 烷烃
酒精 酯化
Carboxylic acids Sodium hydrogen carbonate Salt, water and carbon dioxide

有时,通过反应性鉴定有机化合物是不够的。仅反应性并不能告诉我们有机化合物的结构,这很重要,因为结构决定了化合物的功能!

质子和碳-13 NMR,质谱和红外光谱均可进行,以进行救援!

同样,我们需要考虑这些过程背后的原则。尽管我们不需要在HSC级别上详细了解它,但问自己:“这些技术正在利用有机分子的哪一部分?”

例如,质谱法使用质量到电荷比来确定有机分子的质量。

These processes also come with some funky graphs!

It is absolutely essential that you can not only recognise the features of the graphs but also be able to interpret and draw results from them!

以下是它们的外观示例:

质子NMR图的示例来自Wikipedia。

来自库的碳NMR图的示例。

质谱图来自化学MSU。

红外光谱图来自化学MSU。

Inquiry Question 3: What are the implications for society of chemical synthesis and design?

终于是时候将我们的课堂课进入大世界了!

在这里,我们解决将化学反应引入现实世界所带来的实际复杂性。

我们问自己的问题,例如,我们是否有足够的试剂来满足需求?需要什么反应条件,它们在安全水平范围内?

Most importantly, what are the environmental, social and economical issues that may arise from chemical synthesis?

While it may seem like all these questions are irrelevant to chemistry, it is highly relatable to your building career as a scientist as you start thinking about how your projects may affect people and the world around you.

And this is exactly what the new syllabus wants! The application of theory into real life situations.

3个提示获得频段6的技巧

Tip #1: Memorise your reactions!

如您所知,该模块包含许多不同的反应,以识别有机和无机物质。

有机化学,记住这些的好方法e reactions is to draw a connected flowchart that includes all the types of reactions, with their reactant, products and respective catalysts.

This way you can visually make sense of the overall flow of reactions, while forming a fun summary that is useful for future revision!

For inorganic chemistry, the most you have to memorise is the precipitation rules and the colour of the precipitates. I find that the NAGSAG acronym technique works well in remembering the basic precipitation rules.

要有效地记住,请尝试在时间限制下测试自己!

提示2:确定您的错误并继续练习!

改善回答的关键是检查您在哪里丢失了印记!下一步是问自己或您的标记,为什么您会失去该标记。

But don’t stop there, identifying your mistakes alone is not enough. It’s always best to try the same question again but with the knowledge of what can be improved.

和练习,练习,练习!

每周将自己暴露在新问题上,以熟悉考试风格的问题以及如何编写炸弹回答。

Luckily for you, the majority of this module remains similar to the old module called Monitoring and Management.

So, there should be plenty of past HSC questions you can access through the NESA website.

Tip #3: Work with your peers!

Tackling the entire Chemistry module by yourself can be exhausting, especially with organic chemistry being relatively new with limited resources for study.

因此,不要害怕与同龄人一起工作!小组研究可能是有效的,因为您可以探索可能澄清和巩固您的理解的不同观点或解释。另外,您的朋友可能会向您介绍新资源,这些资源可能很难找到其他资源。

If you’re still feeling unsure about a topic, question or answer, it’s always best to ask your teacher or your tutor. Especially with the funky spectroscopy graphs, your teacher is always the best to go to as they can be tricky to interpret correctly and justify the results.

Plus, discussing with your teacher or tutor is always handy as they can guide you to write a solid Band 6 response that will blow the socks off your marker!
