I can list some uses of chemical analysis

Это примеры инструментальных и "мокрого" анализа методов. Как вы думаете, могут быть использованы эти методы? I can list some uses of chemical analysis (D/E) gel electrophoresis titration flame testing gas chromatography mass spectrometry chemical test tube tests

Which of the following chemical analysis methods are qualitative and which are quantitative? What is the difference? titration flame testing mass spectrometry chemical test tube tests I can describe the difference between qualitative and quantitative analysis and give examples (C)

QUALITATIVE techniques Тестирование опирается на наблюдения. chemical test tube test for sulfates flame testing Я могу описать качественный анализ и привести примеры(C) chemical test tube tests for halides

QUANTITATIVE techniques Testing that relies on measurements. titration Я могу описать количественные анализ и привести примеры(C) gas chromatography mass spectrometry

Types of Instrumental Methods

Nuclear Magnetic Resonance Spectroscopy Спектроскопия ядерного магнитного резонанса(NMR) used for organic compounds. Shows what atoms hydrogen atoms are connected to and helps find structure of the molecule by identifying – OH groups, -NH 2 groups etc.

Disadvantages - Expensive to buy, run and maintain the machines - Дорого купить, эксплуатации и обслуживании машины

4. 3 Chemical Analysis and Titration Objective: - know that modern instrumental methods exist to speed this process Outcomes: All: I can state the two general types of analysis Most: I can describe the difference between qualitative and quantitative analysis and give examples Some: I can name at least two types of instrumental analysis and can explain how they can improve analysis Keywords: qualitative, quantitative, instrumental analysis, Infrared Ultra-violet, chemical analysis, advantages, disadvantages
