net ionic equation

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

• 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.

• Ions and Ionic Bonds

  • Ionic bonds are attractions between oppositely charged atoms or groups of atoms where electrons are donated and accepted.
  • Now, because the number of electrons does not equal the number of protons, each ion has a net charge.
  • This gives it a net charge of -1 since there are now more electrons than protons.
  • Ionic bonds are formed between ions with opposite charges.
  • In the formation of an ionic compound, metals lose electrons and nonmetals gain electrons to achieve an octet.

• 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.

• Net Income

  • Net income in accounting is an entity's income minus expenses for an accounting period.
  • Net income in accounting is an entity's income minus expenses for an accounting period.
  • Net income is a distinct accounting concept from profit.
  • In contrast, net income is a precisely defined term in accounting.
  • As profit and earnings are used synonymously for income (also depending on United Kingdom and U.S. usage), net earnings and net profit are commonly found as synonyms for net income.

• First Condition

  • The first condition of equilibrium is that the net force in all directions must be zero.
  • This means that both the net force and the net torque on the object must be zero.
  • Here we will discuss the first condition, that of zero net force.
  • For example, the net external forces along the typical x- and y-axes are zero.
  • There are horizontal and vertical forces, but the net external force in any direction is zero.

• 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.

  • A continuation of the discussion of periodic properties, including ionic radius and how to predict ionic charges.

• 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.
