<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.

1. What is the best means to separate ammonium chloride, sand, and zinc chloride? And a
ozzi

1. A mixture of ammonium chloride, sand, and zinc chloride should be separated by sublimation.

2. A mixture of zinc chloride and silver chloride should be separated through crystallization.

<h3>What is a separation technique?</h3>

A separation technique can be defined as a technique that is typically used to separate or convert two (2) or more mixture and solution of chemical substances into distinct product such as chemical compounds or elements.

<h3>The types of separation technique.</h3>

In Chemistry, there are various types of separation technique used for the separation of mixtures or solutions and these include:

  • Crystallization
  • Fractional distillation
  • Filtration
  • Evaporation
  • Sublimation
  • Decantation
  • Simple distillation
  • Chromatography

In this scenario, the most effective and efficient means to separate a mixture of ammonium chloride, sand, and zinc chloride is by sublimation from solid to gas state.

On the other hand, the best means to separate a mixture of zinc chloride and silver chloride is through crystallization.
