Solution

The correct option is B
Specific gravity of products

Precipitate formation during a chemical change is dependent on specific gravity of the substances involved in the final products. A precipitation reaction can occur when two solutions containing different salts are mixed, and a cation/anion pair in the resulting combined solution forms an insoluble salt; this salt then precipitates out of solution.
