Question

Of all the reactions you performed, how many resulted in a precipitate and how many did not? Make a general statement about the interaction of aqueous ionic compounds, using the term double-displacement reaction.

Answer 1

Hey, did you ever get the answer?

Answer 2

Double displacement is a type of chemical reaction where two compounds react, and the positive ions (cation) and the negative ions (anion) of the two reactants switch places, forming two new compounds or products.

• Na2s + Hcl ------ Nacl + H2s
• Naoh + CaBr2 -------NaBr + ca(oH)2
