What do you make of this statement: ?Chemistry is all about getting lucky...? I can hear murmurs of approval from those who?ve spent hours in labs trying to figure out why their solution remains colourless while others proudly display their perfect solutions. This week?s site will help you understand the above statement better.

Created by Prof. Fred Senese at the Frostburg State University, W. Maryland, US, General Chemistry Online (http://antoine.frostburg.edu/chem/senese/101) is primarily for first-year chemistry students. But it has much to offer to high school chemistry students and even teachers. The home page gives you that feeling of plenty with a well-organised navigation sidebar on the left. It is a highly readable site and includes many diagrams that help explain complex concepts.

You are presented with an amazing array of topics from chemical bonding and balancing equations to stochiometry and redox reactions. Plus, there is a tutorial with quizzes and drills. But don?t forget to click on the ?Companion Notes? link that provides notes on topics along with learning objectives, and links to all related tutorials, quizzes, and exams on the site. The Exam Survival Guide section will help you breeze through exams by giving you practice tests.

The website is a must-view for the chemistry-minded. Little wonder that it was chosen by Scientific American as the best online resource on chemistry in 2004.
