Answer : The concentration of nitrate ions is 0.450 m.
Solution : Given,
Molarity of = 0.225 m
The balanced ionic equation is,
From the reaction, we conclude that the 1 mole of produces 2 moles of ions. That means the concentration of nitrate ions is twice the value of .
then, 0.225 m of gives 2 × 0.225 of ions
Now the concentration of ions is equal to 0.450 m.
