Chemical Reactions with Phosphoric Acid

Phosphoric acid, represented by the chemical formula H3PO4, can react with various substances. Let's explore its reactions with the given substances:

1. MgO (Magnesium Oxide): Phosphoric acid can react with magnesium oxide. The reaction can be represented as: ``` H3PO4 + MgO → Mg(H2PO4)2 ``` Source: 2. Na2S (Sodium Sulfide): Phosphoric acid can react with sodium sulfide. The reaction can be represented as: ``` H3PO4 + Na2S → H2S + NaH2PO4 ``` Source: No specific source snippet found for this reaction.

3. Mg(OH)2 (Magnesium Hydroxide): Phosphoric acid can react with magnesium hydroxide. The reaction can be represented as: ``` 2 H3PO4 + 3 Mg(OH)2 → Mg3(PO4)2 + 6 H2O ``` Source: 4. Ag (Silver): Phosphoric acid does not react directly with silver. No specific reaction between phosphoric acid and silver was found in the search results provided.

In summary, phosphoric acid can react with magnesium oxide, sodium sulfide, and magnesium hydroxide, but it does not directly react with silver.
