The resulting hydrated ions are represented as Na+(aq)and Cl– (aq).

The resulting hydrated ions are represented as Na+(aq) and Cl–(aq).

Preferably, in step b) H2SO3 (aq) and Li2CO3 (aq) are reacted with each other in substantially equimolar amounts.

Calculate [H+] and [OH−] in a neutral solution at 50.°C.

Calculate [H + ] and [OH − ] in a neutral solution at 50.°C.

The ionic equation is Ba2+(aq) + SO42-(aq) BaSO4(s)

The ionic equation is the same: Ba2+(aq) + SO42–(aq) ==> BaSO4(s)
