Question

H2S04 РЕАГИРУЕТ С : NAOH. MGO. SO2. BA (NO3)2. Kcl. K3po4 Zn. Ni. Cu

Answer 1

1) С NaOH (реакция нейтрализации): H₂SO₄ + 2NaOH --- Na₂SO₄ + 2H₂O;
2) С MgO: H₂SO₄ + MgO --- MgSO₄ + H₂O;
3) С Ba(NO₃)₂: H₂SO₄ + Ba(NO₃)₂ --- BaSO₄ ↓ + 2HNO₃;
4) C Zn: H₂SO₄ + Zn --- ZnSO₄ + H₂ ↑

Answer 2

H2SO4 can react with most of the compounds listed, here are the reactions:

• NaOH: H2SO4 + 2NaOH → Na2SO4 + 2H2O
• MgO: H2SO4 + MgO → MgSO4 + H2O
• SO2: H2SO4 + SO2 → H2S2O7
• Ba(NO3)2: H2SO4 + Ba(NO3)2 → BaSO4 + 2HNO3
• KCl: H2SO4 + 2KCl → 2HCl + K2SO4
• K3PO4: H2SO4 + 2K3PO4 → 3K2SO4 + 2H3PO4
• Zn: H2SO4 + Zn → ZnSO4 + H2
• Ni: H2SO4 + Ni → NiSO4 + H2
• Cu: H2SO4 + Cu → CuSO4 + H2

Note that these reactions are not exhaustive, and there may be other possible reactions with these compounds depending on the conditions under which they are carried out.
