實驗簡介

本實驗的目的係利用DVD空白光碟或廢棄光碟片作為簡易光學分光的元件－反射型光柵，對平行入射光源進行分光。使用日常家用的廢棄紙盒結合DVD光碟，製作一個DVD分光器。藉由肉眼觀察分光器產生的光譜，並且利用具有近焦和自動對焦功能的數位照相機或手機拍攝光譜帶和光譜線。同時嘗試利用自由軟體ImageJ對光譜譜線進行定量分析。

1. Principle:

Rate of reaction can be show as Rate = K[A]^x[B]^y. And then the order of reaction should be x & y, rate constant is a stationary value.

1. Principle:

We want to make zinc reaction with acid but not the iron. So we can use the volumetric of H2 to know how many Zn is used. Dalton's law, means the pressure of a mixture of gases can be disperse by the amount of every gas. Like the follow formula:

1. Principle:

EDTA is a kind of Chemical with 6 ligands, and is used very often. EDTA is also a kind of acid, so sometimes we use H₄Y as EDTA. It is often use with EBT. And we often write down as H₃In and will become H₂In^- in water. When pH is about 7~11, most of it will become HIn^2-,and can catch Ca²⁺, Mg²⁺, Zn²⁺, and Hg²⁺, and become a red chelate. When the pH is more than 11, then HIn^2- will lose one more H and become In^3- (orange).

1. Principle:

We’ll learn how to use lodine to titration the Vitamin C in juice or Vitamin C

1. Principle:

Phenolphthalein（酚酞）is usually used as a pH Indicators, and actually it has 4 different forms in acid or base. We want to use the simple way to make it, and to see how it works. The following is the pH- Phenolphthalein form table.
