What is the net ionic reaction when potassium carbonate is mixed with Calcium bromide?
2 K2CO3 (aq) + CaBr2 (aq) -> 2 KBr (s) + CaCO3 (aq)
2 K2CO3 (aq) + CaBr2 (aq) -> 2 KBr (aq) + CaCO3 (s)
2 K2CO3 (aq) + CaBr2 (aq) -> 2 KBr (aq) + CaCO3 (aq)
2 K+ (aq) + Br- (aq) -> 2 KBr (s)
Ca2+ (aq) + CO32- (aq) -> CaCO3(s)
Only the calcium and carbonate ions are reacting according to the solubility rules to form calcium carbonate.
What is the net ionic reaction when a solution of rubidium sulfate is mixed with barium hydroxide?
Rb2SO4 (aq) + Ba(OH)2 (aq) -> 2 RbOH (aq) + BaSO4 (s)
Rb2SO4 (aq) + Ba(OH)2 (aq) -> 2 RbOH (s) + BaSO4 (aq)
Ba2+ (aq) + SO42- (aq) -> BaSO4 (s)
Rb+ (aq) + OH- (aq) -> RbOH (s)
No Reaction
Only the Ba and sulfate ions will react according to the solubility rules.
What is the net ionic equation that occurs when sodium chloride is mixed with potassium nitrate?
NaCl (aq) + KNO3 (aq) -> NaNO3 (s) + KCl (aq)
NaCl (aq) + KNO3 (aq) -> KNO3 (aq) + KCl (s)
NaCl (aq) + KNO3 (aq) -> NaNO3 (aq) + KCl (aq)
Na+ (aq) + NO3- (aq) -> NaNO3 (s)
No Reaction
Since no precipitation is predicted by the solubility rules, there will be no reaction.
