anonymous · Answer

would it be Na3PO4+ 3 KOH  3 NaOH + K3PO4?

anonymous · Answer

yeah it is. cuz it's not balanced

anonymous · Answer

wait no

anonymous · Answer

You got it right. But it's because sodium cannot switch positions with potassium because its in a lower spot on the metal reactivity serious

hehe k. :p sleep tite

anonymous · Answer

you too :D

anonymous · Answer

i will eventually...

anonymous · Answer

ahaha

jfraser · Answer

whether or not sodium could replace potassium, that's still a valid double displacement reaction. To me, the improper one is #1, calcium chloride is CaCl2, not CaCl.

anonymous · Answer

i go for 2 as @ Beautifulgirl17 said and reason is k is more reactive than Na so it cannot displace it from the compound
