Write the reaction equations: a) Potassium-Potassium hydroxide-Potassium nitrate-Potassium sulfate-Potassium chloride-Potassium b) Sodium-Sodium chloride-Sodium hydroxide-Sodium orthophosphate-Sodium nitrate-Sodium sulfate
а) 1) 2Na + Cl2 → 2NaCl;
2) NaCl + H2O → NaOH + HCl;
3) 3NaOH +H3PO4 → Na3PO4 + 3H2O;
4) Na3PO4 + 3HNO3 → 3NaNO3 + Н3РО4;
5) H2SO4 + 2NaNO3 → Na2SO4 + 2HNO3.
б) 1) 2K + 2H2O → 2KOH + H2↑;
2) KOH + HNO3 → KNO3 + H2O;
3) KNO3+ BaSO4 → K2SO4 + Ba(NO3)2 ;
4) K2SO4 + 2HCl → 2KCl + H2SO4;
5) 2KCl → 2K + Cl2.
