Question

Сколько различных солей можно получить при взаимодействии ортофосфорной кислоты с гидроксидом натрия

Answer 1

Три
Na3PO4, Na2HPO4, NaH2PO4

H3PO4+3NaOH=Na3PO4+3H2O
2H3PO4+NaOH=Na2HPO4+2H2O
H3PO4+NaOH=NaH2PO4+H2O

Answer 2

Number of Different Salts Produced

When orthophosphoric acid reacts with sodium hydroxide, it can produce three different salts. The reaction is as follows:

H3PO4 + 3NaOH → Na3PO4 + 3H2O.

This reaction results in the formation of three different salts: sodium dihydrogen phosphate (NaH2PO4), disodium hydrogen phosphate (Na2HPO4), and trisodium phosphate (Na3PO4).

Therefore, the interaction of orthophosphoric acid with sodium hydroxide can yield three different salts.
