Examples of net ionic equation in the following topics:

  • Precipitation Reactions

    • This is known as the complete ionic equation:
    • A final way to represent a precipitation reaction is known as the net ionic equation.
    • Without the spectator ions, the reaction equation simplifies to the following:
    • Distinguish ways to write precipitation reactions (complete ionic equation and net ionic equation) and use a solubility table to determine whether a precipitation reaction will occur
  • Electrochemical Cell Notation

    • The net ionic equation for the reaction is written:
  • Molecular, Ionic, and Complete Ionic Equations

    • Precipitation reactions can be written as molecular, ionic, or complete ionic equations.
    • The resulting equation is known as the complete ionic equation, and it looks as follows:
    • In this equation, every ion is written out on both sides.
    • This can be simplified to the net or complete ionic equation, which is shown below:
    • Recognize whether a chemical equation is written in molecular, ionic, or complete ionic form.
  • Types of Bonds

    • Pure ionic bonding cannot exist: all ionic compounds have some degree of covalent bonding.
    • Thus, an ionic bond is considered a bond where the ionic character is greater than the covalent character.
    • Bonds with partially ionic and partially covalent character are called polar covalent bonds.
    • If one atom has a higher electronegativity, the electrons will be drawn closer to the nucleus of that atom, resulting in a small net charge around each nucleus of the atoms in the molecule.
    • A rule of thumb is that covalent compounds are more difficult to change than ionic compounds.
  • Naming Ionic Compounds

    • An ionic compound is named first by its cation and then by its anion.
    • In chemistry, an ionic compound is a chemical compound in which ions are held together by ionic bonds.
    • Positive to positive and negative to negative ionic bonds do not occur.
    • Since the net charge of the ionic compound must be zero, the Cu ion has a 2+ charge.
    • The Roman numerals in fact show the oxidation number, but in simple ionic compounds this will always be the same as the metal's ionic charge.
  • Lattice Energy

    • Lattice energy is a measure of the bond strength in an ionic compound.
    • Lattice energy is an estimate of the bond strength in ionic compounds.
    • It is defined as the heat of formation for ions of opposite charge in the gas phase to combine into an ionic solid.
    • Lattice energies are also important in predicting the solubility of ionic solids in H2O.
    • Ionic compounds with smaller lattice energies tend to be more soluble in H2O.
  • Ions

    • Any atom or molecule with a net charge, either positive or negative, is known as an ion.
    • Anions have more electrons than protons and so have a net negative charge.
    • Cations have more protons than electrons and so have a net positive charge.

  • Salt Formation

    • Because of their enhanced acidity, carboxylic acids react with bases to form ionic salts, as shown in the following equations.
    • In the case of alkali metal hydroxides and simple amines (or ammonia) the resulting salts have pronounced ionic character and are usually soluble in water.
  • Electrolysis of Sodium Chloride

    • As we have covered, electrolysis is the passage of a direct electric current through an ionic substance that is either molten or dissolved in a suitable solvent.
    • Well, we can't forget that we have to factor water into the equation.
    • The net process is the electrolysis of an aqueous solution of NaCl into industrially useful products sodium hydroxide (NaOH) and chlorine gas.
  • Salts that Produce Basic Solutions

    • In acid-base chemistry, a salt is defined as the ionic compound that results from a neutralization reaction between an acid and a base.
    • As such, salts are composed of cations (positively charged ions) and anions (negative ions), and in their unsolvated, solid forms, they are electrically neutral (without a net charge).
    • For a generalized anion B-, the net ionic reaction is:
