(1) reaction with indicator: purple litmus test solution turns red when encountering acid, colorless phenolphthalein test solution does not change color when encountering acid

 

(2) exchange reaction with active metal (metal stronger than hydrogen in metal activity sequence table) acid + metal = Salt + hydrogen example: 2HCl + Fe = FeCl2 + H2 ↑

 

(3) react with basic oxide acid + basic oxide → Salt + water 3h2so4 + Fe2O3 = Fe2 (SO4) 3 + 3H2O

 

(4) react with some salts acid + salt → new acid + new salt H2SO4 + BaCl2 = 2HCl + BaSO4 ↓

 

(5) neutralization reaction with soluble alkali: acid + alkali → Salt + water 2HCl + BA (OH) 2 = BaCl2 + 2H2O
