Question

Viết phương trình chứng minh tính axit của H₂SO₃ yếu hơn HCl

Answer 1

PTHH: \(K_2SO_3+2HCl\rightarrow2KCl+H_2O+SO_2\uparrow\)

Answer 2

Carbonic acid is weaker than hydrochloric acid: + If Na2CO3 reacts with HCl, there is a reaction to create NaCl + H2O + CO2 + But if NaCl reacts with H2CO3, it will not create HCl and Na2CO3 => HCl is stronger than H2CO3 Equation (1) also proves that H2CO3 is a weak acid, it decomposes into water and CO2.
