Answer:

nitrite ion is NO2- and nitrate ion is NO3-

Explanation:

The nitrite ion has two oxygen atoms and one nitrogen atom while nitrate ion has three oxygen atoms and one nitrogen atom. They are both univalent negative anions that form compounds with metallic cations as shown below;

Na+ + NO3- ⇒ NaNO3 (sodium nitrate)

Na+ + NO2- ⇒ NaNO2 (sodium nitrite)

Ca2+ + NO3- ⇒ Ca(NO3)2 (calcium nitrate)

Ca2+ + NO2- ⇒ Ca(NO2)2 (calcium nitrite)

You can deduce from the above ionic equations that nitrate ion is NO3- while nitrite ion is NO2-.

Answer:

$BaSO_{4}$ will be not soluble in water

Explanation:

LiOH is a strong base. Hence it gets completely dissociated in aqueous solution.

$NaNO_{3}$ is a strong electrolyte. Hence it gets completely dissociated in aqueous solution.

$MgCl_{2}$ is a strong electrolyte. Hence it gets completely dissociated in aqueous solution.

$K_{2}S$ is a strong electrolyte. Hence it gets completely dissociated in aqueous solution.

$BaSO_{4}$ is a sparingly soluble salt. Hence it is not dissociated and hence dissolved in water. This is due to the fact that both $Ba^{2+}$ and $SO_{4}^{2-}$ ions are similar in size. Hence crystal structure of $BaSO_{4}$ is quite stable. Hence $BaSO_{4}$ is reluctant to undergo any dissociation in aqueous solution.
