Question

Complete the following double replacement reactions (If you want you can use the reference table F to determine if a precipitate will form).

Answer 1

First, let's write the equation of the complete reaction:

CuSO4(aq) + Ba(NO3)2(aq) -> Cu(NO3)2(aq) + BaSO4(s)

According to table F, ions with NO3^2- form soluble compounds, so Cu(NO3)2 will be soluble in water. BaSO4 will precipitate because according to table F, SO4^2- with Ba^2+ is an exception and form a precipitate.

Answer:

C: Yes, the reaction between CuSO4 and Ba(NO3)2 will form a precipitate.

E: According to table F, ions with NO3^2- form soluble compounds, so Cu(NO3)2 will be soluble in water. BaSO4 will precipitate because according to table F, SO4^2- with Ba^2+ is an exception and form a precipitate.

R: The reaction between CuSO4 and Ba(NO3)2 makes aqueous Cu(NO3)2 and solid BaSO4 as products.
