What happens when equal volumes of 0.2M Na2SO3 and 0.2M CaSO3 are mixed?
A. Only Na2S precipitates.
B. Only CaSO3 precipitates.
C. Both CaSO3 and Na2S precipitate.
D. No precipitate forms.
I wonder if you have typed the question incorrectly because the question has Na2SO3 and CaSO3 in it but the answers allude to Na2S and CaSO3.
