If a is slowly added to a solution containing 0.0500 m of b and 0.0500 m of c, which solid will precipitate first? the solubility product constant for a2b3 is 2.30×10−8. the solubility product constant for ac4 is 4.10×10−8. fill in the blanks below.

the [a] when a_2b_3 begins to precipitate is about *blank* the [a] when ac_4 begins to precipitate.
thus, when comparing a_2b_3 the one that will precipitate first is *blank*

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.
