double displacement reaction with 2 examples
Answers
Answer:
Explanation:
A double displacement reaction is a reaction in which two compounds are used as reactants and two compounds are received as products (the anions and cations change thier respective oppositely charged ions) .
For example-
2 KI (aq) + Pb(NO3)2 (aq) →2 KNO3 (aq) + PbI2 (s)
CuSO4 (aq) + 2 NaOH (aq) →Na2SO4 (aq) + Cu(OH)2 (s)
In the first reaction we see that potassium iodide and lead are the two reactants and also their products are two— potassium nitrate and lead iodide (notice that the cations have switched their respective anions).
In the second case, the two reactants are copper sulphate and sodium hydroxide, and after switching thier corresponding anions they give two products— sodium sulphate and copper hydroxide.
