Question

What precipitate is most likely formed from a solution containing ca2+, na+, oh−, and co2−3. what precipitate is most likely formed from a solution containing , , , and . naoh caco3 na2co3 ca(oh)2?

Answer 1

CaCO3

Step-by-step explanation:

i got it right

Answer 2

The solution contains four ions

Ca2+, Na+, OH−, and CO3^-2

so there are following four combinations are possible

NaOH : this is highly soluble in water so will not form precipitate

Ca(OH)2: this is highly soluble in water so will not form precipitate

Na2CO3: again soluble in water so will not form precipitate

CaCO3 : this is not soluble in water (it has low solubility product) so this will form precipitate most likely
