Question

SO3 → H2SO4 → KHSO4 → Na2SO4 .

Answer 1

Ответ:

SO3+H2O= H2SO4

H2SO4+2KOH= KHSO4+ 2H2O

KHSO4+2NaOH= Na2SO4+ KOH+ H2O

Answer 2

This is the chemical equation for the conversion of sulfur trioxide (SO3) to sodium sulfate (Na2SO4) via sulfuric acid (H2SO4) and potassium bisulfate (KHSO4).

The reaction proceeds as follows:

1. SO3 is added to water to produce sulfuric acid (H2SO4):

SO3 + H2O → H2SO4

2. Sulfuric acid reacts with potassium hydroxide (KOH) to produce potassium bisulfate (KHSO4) and water (H2O):

H2SO4 + KOH → KHSO4 + H2O

3. Potassium bisulfate is reacted with sodium chloride (NaCl) to produce sodium sulfate (Na2SO4), potassium chloride (KCl) and water (H2O):

KHSO4 + NaCl → Na2SO4 + KCl + H2O

Overall equation:

SO3 + 2H2O + 2KOH + 2NaCl → 2Na2SO4 + 2KCl + 3H2O
