When silver nitrate (agno3) reacts with sodium sulfate (na2so4) in aqueous solution, will a precipitate form? if yes, what is the precipitate?

The correct answer is Yes, will precipitate.

Explanation:

Double displacement reaction is defined as the reaction in which exchange of ions takes place.

Precipitate is the insoluble salt that is formed when two different solutions are mixed together. It settles down at the bottom of the flask after some time.

The chemical equation for the reaction of sodium sulfate and silver nitrate follows:

Silver sulfate emerges as a solid and settles down and is considered as a precipitate.

Hence, the correct answer is Yes, will precipitate.

explanation:

metals have excess of electrons whereas non-metals have deficiency of electrons. thus, in order to gain stability metals easily donate their electrons to the non-metals.

for example, electronic configuration of sodium is and electronic configuration of phosphorous is .

when a phosphorous atom and sodium atom combine together then sodium will donate is extra one electron to the phosphorous atom. as a result there will be formation of ionic bond between sodium and phosphorous.

the reaction will be as follows.

there, are three sodium sodium atoms and each of them will donate its one extra electron to phosphorous atom. thus, the sub-shell of phosphorous gets completely filled.  

thus, we can conclude that electrons are transferred from atoms of sodium to atoms of phosphorous. this transfer makes the sodium atoms donate one electron and the phosphorous atoms to gain one electron. as a result, the sodium and phosphorus atoms strongly attract each other.
