Question

1.NaOH+H3PO3= 2.NaOH+SO3= 3.NaOH+P2O5=

Answer 1

H3PO3 + 3 NaOH = Na3PO3 + 3 H2O

Если NAOH в избытке ,то : NaOH+SO3-->NaHSO4 

Если SO3 в избытке ,то : 2NaOH+SO3 --> Na2SO4+H2O

 

NaOH+P2O5=Na3PO4+H2O

Answer 2

1. NaOH + H3PO3: The reaction between sodium hydroxide (NaOH) and phosphorous acid (H3PO3) can be represented by the following balanced equation:

3NaOH + H3PO3 → Na3PO3 + 3H2O

In this reaction, sodium hydroxide reacts with phosphorous acid to form sodium phosphite and water.

2. NaOH + SO3: The reaction between sodium hydroxide (NaOH) and sulfur trioxide (SO3) is not a direct reaction. Sodium hydroxide is a strong base, while sulfur trioxide is a highly reactive acidic oxide. Their reaction would result in the formation of a compound other than a simple salt. If you can provide more information or context about the reaction conditions or the desired reaction product, I can provide a more specific answer.

3. NaOH + P2O5: The reaction between sodium hydroxide (NaOH) and diphosphorus pentoxide (P2O5) can be represented by the following balanced equation:

2NaOH + P2O5 → 2NaPO3 + H2O

In this reaction, sodium hydroxide reacts with diphosphorus pentoxide to form sodium metaphosphate and water.
