Which ion will most likely form a precipitate when reacted with SO42 ?

Charra [1.4K]

<h2>Answer:Ba $^2+$ </h2>

Explanation:

option A:

$SO_{4}^{2-}$ is an anion and $Cl^{1-}$ is also an anion.So,there is no reaction.

option B:

$K^{+}$ reacts with $SO_{4}^{2-}$ to form $K_{2}SO_{4}$ .

Since $K$ is a first group element,all its salts are soluble in water.

Hence no precipitate is formed.

option C:

$Na^{+}$ reacts with $SO_{4}^{2-}$ to form $Na_{2}SO_{4}$ .

Since $Na$ is a first group element,all its salts are soluble in water.

Hence no precipitate is formed.

option D:

$Ba^{2+}$ reacts with $SO_{4}^{2-}$ to form $BaSO_{4}$ .

Solubility of sulphates of second group elements decrease down the group.

So, $BaSO_{4}$ is a precipitate.

What describes the pool of electrons in metallic bonding?

puteri [66]

In metallic bonding, the electrons are “surrendered” to a common pool and become shared by all the atoms in the solid metal. Metallic bonding is found in metals and their alloys. When the atoms give up their valence electrons, they form ions. These ions are held together by the electron cloud surrounding them.
