Question

what happen if 2 in soluble compound or mix in water will reaction take place​

Answer 1

Answer:

A precipitation reaction occurs when two ionic compounds are dissolved in water and form a new ionic compound that does not dissolve; this new compound falls out of solution as a solid precipitate. The formation of a solid precipitate is the driving force that makes the reaction proceed.

Explanation:

Answer 2

Explanation:

If both of the products are SOLUBLE, no reaction will occur and all of the ions will remain in solution. ... Then it is insoluble. So the Lead and Iodide ions remain together and since it is insoluble, it precipitates out of solution and a reaction occurs
