Precipitation Reactions Flashcards
1
Q
What is dissociation
A
Dissociation is what happens when an ionic solid dissolves.
The solvent molecules surround the ions in the lattice and break it apart
When ions are dissolved in a solution the subscript (aq) for aqueous is used to show that the ions are dissolved in water
2
Q
What are precipitation reactions
A
When two ionic compounds are mixed, the ions sometimes react to form an insoluble solid called a precipitate
3
Q
Why do precipitate reactions occur
A
Because there is a stronger attraction between the ions forming the solid.= than the ions and the solvent
4
Q
What is conservation of mass
A
Matter cannot be created or destroyed
This means that the number of atoms in the reactants is always equal to the number of atoms in the products
