What are the products formed when Ba2+ reacts with HCO3-? I think the equation will be
Ba2+ + HCO3- ----> BaCO3 + H+ .  May I confirm if this is correct? I read from an online source that HCO3- decides it will be better off with the Ba2+ (more stable due to equal charge) and will thus frees itself to bond by releasing H+ so as to form BaCO3. I don't understand why this is the case. Or are there other reasons to explain the products formed when Ba2+ reacts with HCO3-?

It's Ba(HCO3)₂

[Borek]

It's Ba(HCO3)₂

You should check Ksp and Ka2 to be sure if it is not

Ba²⁺ + HCO₃^- -> BaCO₃ + H⁺

[sci994]

I think this is OK
2NaHCO₃ + Ba(OH)2  2NaOH + Ba(HCO₃)₂
Ba²⁺+HCO₃^2-

Can u write down one ex. Ba2+ + HCO3- -> BaCO3 + H+?

In the reaction of Ba(OH)2 with NaHCO3 practically only BaCO3 is formed.
but Ba salts form barium hydrogencarbonate
