Which of the following substances: calcium hydroxide, magnesium, carbon monoxide (IV), sulfuric acid, aluminum phosphate will phosphoric acid interact? Write the equations of possible reactions.

1) 2H3PO4 + 3Ca (OH) 2 → Ca3 (PO4) 2 + 3H2O (calcium phosphate, the reaction is going on, since the bases react with acids – the neutralization reaction).

2) 2H3PO4 + 3Mg → Mg3 (PO4) 2 + 3H2 (magnesium phosphate, hydrogen; the reaction proceeds, since acids react with all metals in the range of activity to hydrogen).

3) H3PO4 + CO2 → the reaction does not go, since acids do not react with acid oxides.

4) H3PO4 + H2SO4 → the reaction does not proceed, since the acids do not react with each other.

5) H3PO4 + 2AlPO4 → Al2 (HPO4) 3 (aluminum hydrogen phosphate).
