THE CLASSIFICATION OF CHEMICAL REACTIONS Danny Bhatt SCH3U0-G Mr. Gandhi Wednesday‚ April 1st‚ 2014 INTRODUCTION The purpose of this lab is to determine the different types of chemical reactions and differentiate between them based on similar characteristics of each set category. In this lab it is hypothesized that every chemical reaction which was observed would fall under already set categories (that are: synthesis‚ decomposition‚ single displacement‚ double displacement‚ combustion and

lower level which makes the color back to normal. In order to determine the identity of several unknowns‚ I will perform flame tests and then use my data and observations. Background In this Unit‚ I am studying the election configurations such as Barium‚ Copper‚ Lithium‚ Potassium‚ and ects. I studied wavelengths in the visible spectrum. I also studied a characteristic color in a flame test and energy changes of electrons. Procedure 1. Put on lab apron. 2. A half amount of water was added to

AIM: To outline what a precipitation reaction is‚ describe ways which one can predict whether a precipitation reaction would form or not‚ describe the uses of precipitation reactions in everyday activities and industries BACKGROUND INFORMATION: Precipitation is the formation of a solid in a solution during a chemical reaction‚ such as evaporation. A substance that causes precipitation when it is added to a solution is called a precipitant. This can occur when an insoluble substance is formed in

combined with Co(NO3)2 or cobalt nitrate. Furthermore‚ most copper and iron nitrates‚ even with differing sodium compounds produced a precipitate. Exceptions were Cu(NO3)2 with sodium sulfate and sodium chloride. It was also noticed that nickel‚ barium‚ and iron nitrates (excluding those with few with no reaction) across the board had the same color precipitates no matter the sodium compound that it was mixed with.
