Metathesis reaction aqueous solutions, skills to develop
Hint - Use the following one-line method to do the conversion quickly.
The new couples form a precipitation, gas, or neutral molecules. Metathesis reaction takes place in solution!
Therefore, a solubility chart or general knowledge of solubility rules can be used to predict whether two aqueous solutions will react. Thus, a gas is formed.
Illustrative is the exchange of the counteranion in ferrocenium tetrafluoroborate to a more lipophilic borate salt, which is soluble in aromatic solvents: What is the weight of 0.
You can assume x be the weight g of CaCl2, then 3.
Cations are always attracted to anions, but the hydration and hydrogen bonding keep the ions of electrolytes in solution. If they form a more stable substance such as a solid or neutral molecules, exchange or metathesis reaction takes place.
