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.

Mechanical energy is the top suject while it has two types: Kinetic energy which is the energy in motion and potential energy which is the energy in reserve. The measure of both energy in motion and reserve is called Joules. Joules then is the International System of Measurement unit for energy, this is mainly used to account for scaling energy in all aspects.

Would an alkaline earth metal make a good replacement for tin in a tin can?

hichkok12 [17]

Answer:

Definitely not. This is because the alkaline earth metal [basically group 2 elements] are reactive and will react with the contents of the can, contaminating it.
