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

    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

    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.

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