Final answer:
A precipitate is a solid with low solubility that forms when ionic solutions are mixed in double replacement reactions. It is formed by the combination of cations and anions from the reactants to form an insoluble ionic compound. Precipitates can be separated from the remaining fluid using filtration, centrifuging, or decanting.
Step-by-step explanation:
A precipitate is a solid with low solubility that sometimes forms when ionic solutions are mixed. It is formed when the cations from one reactant combine with the anions from the other reactant to form an insoluble ionic compound.
Precipitates are typically formed in double replacement reactions, where the reactants dissociate and bond with the respective anion or cation from the other reactant.
The solid precipitate can be separated from the remaining fluid through various methods such as filtration, centrifuging, or decanting.
