koban [17]

Answer:

$Ca^{2+} and Co^{2+}$

Explanation:

Given:

A solution contains one or more of the following ions such as Ag, $Ca_2$ and $Co_2$

Here the Lithium bromide is added to the solution and no precipitate forms

Solution:

Since with LiBr no precipitation takes place therefore Ag+ is absent

Here on adding $Li_2SO_4$ to it precipitation takes place.

Precipitate is as follows,

$Ca^{2+}(aq)+SO_4^2^-(aq)----->CASO_4(s)$

Thus,

$Ca^2^+$ is present

When $Li_3PO_4$ is added again precipitation takes place.

Therefore the reaction is as follows,

$Co^2^+(aq)+PO_4^3^-(aq)------>Co_3(PO_4)_2(s)$

Therefore,

$Ca^{2+} and Co^{2+}$ are present in the solution

Draw a drawing representing the reaction that occurs between calcium nitrate and sodium oxalate

Flura [38]

Reaction between Calcium Nitrate and Sodium oxalate results in the formation of Sodium nitrate and Calcium Oxalate through Double displacement reaction.

<h3>What is Double displacement reaction ?</h3>

A double displacement reaction is a type of chemical reaction in which the reactant ions exchange places to form new products.

Usually, a double displacement reaction results in precipitate formation.

The chemical bonds between the reactants may be either covalent or ionic.

Drawing representing the reaction that occurs between calcium nitrate and sodium oxalate is attached as figure.
