The reaction series includes single replacement, double replacement, synthesis, and decomposition reactions. This is one type of oxidation-reduction reaction, or redox reaction, because it occurs via a transfer of electrons. Record your observations. For each of the reactions performed, predict the reaction type (single or double displacement) record your observations; predict the names and states of the products formed; write the balanced “molecular” equation, including all physical states. For a reaction to proceed to completion all of the reactants must mix: they may need to be stirred, or heated to assist in the process of them reacting. Driving forces for double replacement reaction is formation of water, gas or a solid.
In Part A of this lab we will examine single replacement reactions. What is a single replacement reaction? First: classify the reaction as a main type: either synthesis, decomposition, combustion, single replacement OR double replacement. In single displacement reaction, any one chemical partner exchanges from reactants to products while two sets of chemical partners exchanges from reactants to products. The drop bottles contained different compounds which were dropped into the spot plates and mixed together. 3 CaCl 2 (aq) + 2 Na 3 PO 4 (aq) → 1 Ca 3 (PO 4)2(s.
During the reaction, the element replaces the anion or the cation in the compound. These are synthesis, decomposition, combustion, single replacement and double replacement.
