Chemical Analysis

Yoz, everyone,

Since you have 2 'free' days, I think you can afford some time to do some reading.

As I've mentioned in class, there are 2 types of chemical analysis - Qualitative (what?) and Quantitative (how much?).

In class, you've learnt chemical methods to detect ions. But, what are some limitations of these tests? How to chemists overcome these limitations?

To help detect really small quantities, machines have been invented. One such machines is the Atomic Absorption Spectrometer (AAS). The AAS not only identifies the metal (e.g. elemental or ionic form) present, but also tells the quantity that is present. Read this for more.

Those who are keen to find out more about analytical chemistry, you could read this. It includes the various work done by analytical chemist.

Enjoy ur weekends!

Rain rain come this way!

Hi.

In class, we discussed the importance of salts. Do you know that salts (like silver iodide and calcium chloride) are used in cloud-seding to cause rain to fall?

Quite an interesting technology that you might want to read up. What happens to the salts as they fall onto the ground? Will they cause pollution? Read this for more.
