bacl2 + h2so4

When barium chloride (BaCl2) reacts with sulfuric acid (H2SO4), it forms barium sulfate (BaSO4) and hydrochloric acid (HCl) as shown in the following balanced chemical equation:

BaCl2 + H2SO4 → BaSO4 + 2HCl

This reaction is a double displacement reaction, where the positive ions switch places between the two reactants to form the products.
