Sulfuric acid is considered incompatible with water if water is added to concentrated H 2 SO 4. (Always add concentrated acid to water.) Sulfuric acid should not be readily mixed with the alkalis - caustic soda, caustic potash, soda ask, lime, and limestone. Sodium hypochlorite reacts with H 2 SO 4 to yield chlorine gas (Cl 2), which is hazardous.
