A Synthesis Experiment

Your laboratory experiments can be classified to two major types a technique experiment or a synthesis experiment. Each requires different handling. 

In a technique experiment, you get to practice a certain operation before you have to do it in the course of a synthesis. Distilling a mixture of two liquids to separate them is a typical technique experiment. 

Read the following handwritten notebook pages with some care and attention to the typeset notes in the margin. A thousand words are worth a picture or so (Figs. 2-4). 

Use a descriptive title for your experiment. Distillation. This implies you ve done all there is in the entire field of distillation. You haven t Perhaps all you ve done is The Separation of a Liquid Mixture by Distillation. Hmmmmmm. 

Writing that first sentence can be difficult. Try stating the obvious.

In a synthesis experiment, the point of the exercise is to prepare a clean sample of the product you want. All the operations in the lab (e.g., distillation,... 

The composition and the basicity of the synthesis gel, the presence of mineralizing agents and salts or ion pairs and template molecules, the synthesis temperature and time, are all important parameters determining the outcome of a synthesis experiment in terms of nature of the crystalline phase, composition and compositional homogeneity, purity, size, and morphology of the crystals [98]. The typical chemical composition of a synthesis hydrogel, commonly expressed in terms of molar composition of the oxides, is as follows ...
