Which of the following compounds is neutral in aqueous solution?

A. CaCl2

B. AlCl3

C. NH4Cl

D. CaO

E. Na2CO3

F. CO2

  • Chemistry -

    What do you mean by neutral?
    For example, CaCl2 has as many + charges on the Ca ion as - charges on the Cl ion.
    The same is true for B, C, D, E,

    Or could you mean neutral acid/base.
    The only one is CaCl2.

    Or some other meaning for neutral?
