Which of the listed substances will interact with a sulfuric acid solution: zinc, iron oxide (3), iron hydroxide (3), mercury, potassium chloride, magnesium hydroxide, barium nitrate, phosphorus oxide (5), potassium carbonate. Write down possible reactions.

1) H2SO4 (dil.) + Zn → ZnSO4 + H2.

2) 3H2SO4 + Fe2O3 → Fe2 (SO4) 3 + 3H2O.

3) 3H2SO4 + 2Fe (OH) 3 → Fe2 (SO4) 3 + 6H2O.

4) H2SO4 + Hg → the reaction does not take place, since dilute sulfuric acid does not react with metals that are in the line of metal activity after hydrogen.

5) H2SO4 + KCl → the reaction does not take place, since no gas, precipitate or weak electrolyte is formed.

6) H2SO4 + Mg (OH) 2 → MgSO4 + 2H2O.

7) H2SO4 + Ba (NO3) 2 → 2HNO3 + BaSO4.

8) H2SO4 + P2O5 → the reaction does not take place, since acids do not react with acid oxides.

9) H2SO4 + CaCO3 → CaSO4 + CO2 + H2O.
