Consider the neutralization reaction between potassium carbonate, K2CO3, and hydrobromic acid, HBr, forming the salt potassium bromide, KBr, carbon dioxide, CO2, and water, H2O. The balanced chemical equation for the reaction is K2CO3(aq)+2HBr(aq)→2KBr(aq)+CO2(g)+H2O(l) In the reaction, K2CO3, HBr, and KBr are strong electrolytes, so these compounds dissociate completely in water to form their respective ions. The total ionic equation is 2K+(aq) + CO32−(aq) + 2H+(aq) + 2Br−(aq)→2K+(aq) + 2Br−(aq) + CO2(g) + H2O(l) To obtain the net ionic equation, the...
