Concept explainers
Write net ionic equations for the following molecular equations. HBr is a strong electrolyte.
- a HBr(aq) + NH3(aq) → NH4Br(aq)
- b 2HCl(aq) + Ba(OH)2(aq) → 2H2O(l) + BaCl2(aq)
- c Pb(NO3)2(aq) + 2NaBr(aq) → PbBr2(s) + 2NaNO3(aq)
- d MgCO3(s) + H2SO4(aq) → MgSO4(aq) 1 H2O(l) + CO2(g)
(a)
Interpretation:
To write the complete and net ionic equations for the given set of molecular equations.
Concept introduction:
A chemical equation is the figurative representation of chemical reaction. In a chemical equation the reactants are in the left side and the products are in the right side. A balanced chemical equation serves as an easy tool for understanding a chemical reaction. There are mainly three types of chemical equations, molecular equations, complete ionic equation and net ionic equation.
In molecular equations the reactants and products are represented as molecular substances, even though they exist as ions in solution phase. The molecular equation for the reaction between
This equation is helpful in understanding the reactants and products involved in the reaction.
In complete ionic equations the electrolytes are represented as its ions. Soluble compounds exist as ions in solution. Complete ionic equation is helpful in understanding the reaction at ionic level. The complete ionic equation for the reaction between
The solid
In net ionic equations the ions that are common in the reactant and product sides( Spectator ions) are cancelled. These spectator ions are not participating in the chemical reactions. The net ionic equation for the reaction between
Answer to Problem 4.34QP
The net ionic equation
Explanation of Solution
The molecular equation for the reaction between
The ions common in the reactant and the product side are cancelled from the total ionic equation to get net ionic equation.
(b)
