recognize keolistravelservices.comical reactions as single-replacement reactions and double-replacement reactions. Use the routine table, an activity series, or solubility rule to predict even if it is single-replacement reaction or double-replacement reactions will certainly occur.

You are watching: How to predict single replacement reactions


Up until now, we have actually presented keolistravelservices.comistry reactions together a topic, however we have actually not debated how the products of a keolistravelservices.comistry reaction can be predicted. Below we will begin our research of certain varieties of keolistravelservices.comical reactions that enable us to predict what the assets of the reaction will be.

A single-replacement reaction is a keolistravelservices.comistry reaction in which one element is substituted for an additional element in a compound, generating a brand-new element and also a brand-new compound together products. Presented below:

is an instance of a single-replacement reaction. The hydrogen atom in (ceHCl) are replaced by (ceZn) atoms, and also in the procedure a new element—hydrogen—is formed. An additional example of a single-replacement reaction is

Here the negatively fee ion alters from chloride come fluoride. A common characteristic the a single-replacement reaction is that there is one aspect as a reactant and another facet as a product.

Not every proposed single-replacement reactions will certainly occur in between two given reactants. This is most easily demonstrated with fluorine, chlorine, bromine, and also iodine. Collectively, these elements are called the halogens and are in the next-to-last obelisk on the periodic table (Figure (PageIndex1)). The aspects on height of the column will change the facets below lock on the periodic table, however not the other way around. Thus, the reaction stood for by

will occur; however the reaction

will not, because bromine is below fluorine ~ above the periodic table. This is simply one of countless ways the routine table helps us to know keolistravelservices.comistry.

Part double-replacement reactions are obvious because you have the right to see a solid precipitate coming out of solution.
