Metathesis reactions key words: metathesis, precipitation, neutralization, gas formation , exchange or metathesis reaction takes place.
Reactions in which two compounds react to form two new compounds, with no changes in oxidation number reactions in which the ions of two compounds exchange partners. A salt metathesis reaction (from the greek μετάθεσις, transposition), sometimes called a double replacement reaction or double displacement reaction, is a. Why do ions exchange partners cations are always attracted to anions, but the hydration and hydrogen bonding keep the ions of electrolytes in solution.
