1. Aim: To determine the weight-to-volume percent of acetic acid present in commercial vinegar and the weight-to-volume percent of ammonia present in window cleaners. Acid-base titrations can be conducted using the above samples against standardized aqueous NaOH and standardized aqueous HCl solutions respectively. 2. Introduction: Acetic acid‚ commonly known as ethanoic acid CH3COOH‚ is found in commercial vinegar. It is a weak organic acid that gives vinegar its characteristic pungent smell‚

The Power of Knowledge Our present day cabinet of curiosities (the "Cabinet") is akin to early modern representations‚ which contained a vast range of objects representing the power of divine creation‚ in that the Cabinet represents‚ through its display of five objects‚ the power of human knowledge. Each of these objects helps mankind acquire and/or use knowledge. The order of objects displayed has been designed to reflect the evolution and utilisation of knowledge: an illustration of the DNA spiral

On the other hand‚ politics‚ at first as the making of decision‚ has a second characteristic

Acids vs Bases In chemistry‚ when some elements are mixed‚ the compounds that are formed can be classified depending on its characteristics‚ just like acids and bases. Acids are defined as compounds that donate a hydrogen ion‚ H+‚ to another compound. Bases are the chemical opposite of acids. They both are different in many ways. One way in which acids and bases differ is the pH and the pOH. The pH is a number used to denote the hydrogen-ion concentration‚ or the acidity‚ of a solution. In the

Why would anyone feel the need to write an entire book on such a mundane topic such as sugar? Look around at some food products you might have and you will realize that many if not all of them contain sugar in some form or another. For example‚ a can of soda‚ which most people drink everyday‚ contains (depending on the brand) approximately 40 grams of sugars. Look further and you might find that even things such as cheese or chips or soup contain several grams of sugar in them. The wide diversification
