Answer:

1,380 °C hope this is the right answer

[tex]\boxed{\sf \Delta T_f=K_fm\times i}[/tex]

  • i is vant of factor

For K_3 PO_4

It shall release 3K+ and PO_4- ions

  • So vant Hoff factor is 4

Now

[tex]\\ \rm\Rrightarrow \Delta T_f=1.56(4)(1.86)[/tex]

[tex]\\ \rm\Rrightarrow \Delta T_f=11.6°C[/tex]

It can be freezed easily at room temperature in UK or Siberia
