8. Which of the following pairs of compounds would form a precipitate when their aqueous solutions are mixed?
A. NaCl and KNO3
B. KCL and NaNO3
C. K2SO4 and BaCl2
D. NH4NO3 and CO3
Not A Because Salts of Na & K are Soluble
Not B for same reason.
BaSO4 is insoluble.
Myschool, the correct answer should be C cos potassium sulphate and barium chloride in aqueous solutions will give a white precipitate of barium sulphate and potassium chloride.
The answer suppose to be "C" because potassium sulphate & barium chloride form a White precipitate in aqueous solution and also insoluble in their state.
My school app, there are so many errors in this chemistry WAEC questions and answers.
If care is not taken, I will leave this website for good and not for bad.👈
