Which of the following is not a correct chemical equation for a double displacement reaction? CaCl + LiCO3 CaCO3 + LiCl
Na3PO4 + 3 KOH 3 NaOH + K3PO4
2 MgI2 + Mn(SO3)2 2 MgSO3 + MnI4
2 RbNO3 + BeF2 Be(NO3)2 + 2 RbF

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
