## Identify the ions that exist in each aqueous solution, and specify the concentration of each ion.(a) 0.25 M(NH4)2SO4(b) 0.123 M Na2CO3(c) 0.056 M HNO3

(a)

Interpretation Introduction

Interpretation:

The ions that exist in aqueous solution of 0.25 M (NH4)2SO4 has to be determined.  Concentration of each ion has to be determined.

Concept introduction:

• Concentration of solutions can be expressed in various terms; molarity is one such concentration expressing term.
• Molarity (M) of a solution is the number of gram moles of a solute present in one liter of the solution.

Molarity=NumberofmolesofelementVolumeofsolutioninlitres

• A solution containing one gram mole or 0.1 gram of solute per litre of solution is called molar solution.
• Amount of substance (mol) can be determined by using the equation,

Numberofmole=GivenmassofthesubstanceMolarmass

• The molar mass of an element or compound is the mass in grams of 1 mole of that substance, and it is expressed in the unit of grams per mol (g/mol).
• For chemical reaction balanced chemical reaction equation written in accordance with the Law of conservation of mass.
• Law of conservation of mass states that for a reaction total mass of the reactant and product must be equal.

### Explanation of Solution

One mole of (NH4)2SO4 compound contains two moles of NH4+ and 1molofSO42-.  In solution the compound dissociates and the balanced chemical reaction equation for this can be written as,

(NH4)2SO42NH4++SO42-

So the ions that exist in the 0
