Question

for the following reaction=?

BaBr2 (aq) + Na2SO4(aq) =>?

i have no idea how i would write the NET

Explanation / Answer

First, write the balance equation:         BaBr2(aq) + Na2SO4(aq) -->BaSO4(s) + NaBr(aq) Then, rewrite it as ion, notice that only aqueous can dissociation.Solid, gas can't.          Ba2+(aq) + 2Br-(aq) + 2Na+(aq) +SO42-(aq) --> BaSO4(s) +Na+(aq) + Br-(aq) Then cancel out these ions that appears as reactants and products(spectator ions) in equation. Then, you have net ionic equation:                            Ba2+( aq) + SO42-(aq) -->BaSO4(s)       Hope it helps you.
