Chapter 4, Problem 4.59QP

(a)

Interpretation Introduction

Interpretation: The balanced molecular equation and net ionic equation for the given reactions is to be stated.

Concept introduction: A balanced chemical equation is based on the law of conservation of mass for a closed system. According to this law, the mass of the products formed in a chemical reaction is equal to the mass of the reactants involved in the reaction.

In net ionic equations the same ions that are present on both the sides of reaction are cancelled out.

To determine: The overall ionic and net ionic equation for the given reaction.

Answer to Problem 4.59QP

Solution

The balanced reaction between H2SO4 and Mg(OH)2 is,

H2SO4(aq)+Mg(OH)2(aq)MgSO4(aq)+2H2O(l)

The net ionic equation is,

HSO4(aq)+H+(aq)+Mg(OH)2(aq)Mg2+(aq)+SO42(aq)+2H2O(l)

Explanation of Solution

Explanation

When an acid reacts with a base it forms a salt and water and this type of reaction is known as neutralization reaction.

According to the solubility rules, magnesium hydroxide act as a weak electrolyte as it is insoluble in water and only some ions go into solution.

The complete reaction between H2SO4 and Mg(OH)2 is,

H2SO4(aq)+Mg(OH)2(aq)MgSO4(aq)+H2O(l)

According to the law of conservation of mass, the mass of the reactants that take part in a chemical reaction is equal to the mass of the products formed in the reaction.

In the given reaction, the number of magnesium and sulphur atoms present on the reactant side is equal to their number on the product side. The number of oxygen and hydrogen atom present on the reactant side is not equal to their number on the product side. The coefficient 2 is added to H2O present on product side. This balances the number of, oxygen, and hydrogen atoms on either side of the reaction.

The balanced reaction between H2SO4 and Mg(OH)2 is,

H2SO4(aq)+Mg(OH)2(aq)MgSO4(aq)+2H2O(l)

The dissociation reaction of H2SO4 is,

H2SO4(aq)H+(aq)+HSO4(aq)

In overall ionic reaction all the ions that are taking part in a reaction is represented in an equation.

Therefore, the overall ionic reaction is,

HSO4(aq)+H+(aq)+Mg(OH)2(aq)Mg2+(aq)+SO42(aq)+2H2O(l)

The ions that are present on both sides of the reaction are called spectator ions and are omitted from the reaction to represents the actual reactants and product.

Hence, the net ionic equation is,

HSO4(aq)+H+(aq)+Mg(OH)2(aq)Mg2+(aq)+SO42(aq)+2H2O(l)

Answer to Problem 4.59QP

Solution

The balanced reaction between HCl and MgCO3 is,

2HCl(aq)+MgCO3(aq)MgCl2(aq)+H2CO3(l)

The net ionic equation is,

2H+(aq)+MgCO3(aq)Mg2+(aq)+H2O(l)+CO2(aq)

Explanation of Solution

Explanation

When an acid reacts with a base it forms a salt and water and this type of reaction is known as neutralization reaction.

According to the solubility rules, magnesium carbonate act as a weak electrolyte as it is insoluble in water and only some ions go into solution.

The complete reaction between HCl and MgCO3 is,

HCl(aq)+MgCO3(aq)MgCl2(aq)+H2CO3(l)

According to the law of conservation of mass, the mass of the reactants that take part in a chemical reaction is equal to the mass of the products formed in the reaction.

In the given reaction, the number of carbon magnesium and oxygen atoms present on the reactant side is equal to their number on the product side. The number of hydrogen and chlorine atom present on the reactant side is not equal to their number on the product side. The coefficient 2 is added to HCl present on reactant side. This balances the number of, oxygen, and hydrogen atoms on either side of the reaction.

The balanced reaction between HCl and MgCO3 is,

2HCl(aq)+MgCO3(aq)MgCl2(aq)+H2CO3(l)

In overall ionic reaction all the ions that are taking part in a reaction is represented in an equation.

The dissociation of HCl is,

HCl(aq)H+(aq)+Cl(aq)

The dissociation of carbonic acid is,

H2CO3H2O(l)+CO2(aq)

Therefore, the overall ionic reaction is,

2H+(aq)+2Cl(aq)+MgCO3(aq)Mg2+(aq)+2Cl(aq)+H2O(l)+CO2(aq)

The ions that are present on both sides of the reaction are called spectator ions and are omitted from the reaction to represents the actual reactants and product.

Hence, the net ionic equation is,

2H+(aq)+MgCO3(aq)Mg2+(aq)+H2O(l)+CO2(aq)

Answer to Problem 4.59QP

Solution

The balanced reaction between HCl and MgCO3 is,

HCl(g)+NH3(g)NH4Cl(g)

The net ionic equation is,

HCl(g)+NH3(g)NH4Cl(g)

Explanation of Solution

Explanation

When an acid reacts with a base it forms a salt and water and this type of reaction is known as neutralization reaction.

The complete reaction between HCl and NH3 is,

HCl(g)+NH3(g)NH4Cl(g)

According to the law of conservation of mass, the mass of the reactants that take part in a chemical reaction is equal to the mass of the products formed in the reaction.

In the given reaction, the number of nitrogen, hydrogen and chlorine atoms present on the reactant side is equal to their number on the product side. Therefore the above reaction is a balanced reaction.

The balanced reaction between HCl and MgCO3 is,

HCl(g)+NH3(g)NH4Cl(g)

Since, no aqueous solution is present; there is no need to show ions in the equation.

Therefore, the molecular equation and net ionic equation is same.

Hence, the net ionic equation is,

HCl(g)+NH3(g)NH4Cl(g)

Explanation of Solution

Explanation

When an acid reacts with a base it forms a salt and water and this type of reaction is known as neutralization reaction.

The complete reaction between H2O and SO3 is,

SO3(g)+H2O(l)H2SO4(aq)

The reaction between H2SO4 and NaOH is,

H2SO4(aq)+NaOH(aq)Na2SO4(aq)+2H2O(l)

According to the law of conservation of mass, the mass of the reactants that take part in a chemical reaction is equal to the mass of the products formed in the reaction.

In the given reaction, the number of sulphur atoms present on the reactant side is equal to their number on the product side. The number of hydrogen, oxygen and sodium atom present on the reactant side is not equal to their number on the product side. The coefficient 2 is added to NaOH present on reactant side and coefficient 2 is added to H2O present on the product side. This balances the number of sodium, oxygen, and hydrogen atom on either side of the reaction.

The balanced reaction between HCl and MgCO3 is,

H2SO4(aq)+2NaOH(aq)Na2SO4(aq)+2H2O(l)

In overall ionic reaction all the ions that are taking part in a reaction is represented in an equation.

The first dissociation reaction of H2SO4 is,

The second dissociation reaction of H2SO4 is,

HSO4(aq)H+(aq)+SO42(aq)

The dissociation reaction of NaOH is,

Therefore, the overall ionic reaction is,

H+(aq)+HSO4(aq)+2Na++2OH(aq)2Na+(aq)+SO42(aq)+2H2O(l)

The ions that are present on both sides of the reaction are called spectator ions and are omitted from the reaction to represents the actual reactants and product.
