What is a balanced net ionic equation?
The net ionic equation is the chemical equation that shows only those elements, compounds, and ions that are directly involved in the chemical reaction. Net ionic equations must be balanced by both mass and charge. Balancing by mass means making sure that there are equal numbers of each element.
What is meant by ionic equation?
Similar to a molecular equation, which expresses compounds as molecules, an ionic equation is a chemical equation in which the electrolytes in aqueous solution are expressed as dissociated ions. Additionally, the net charge is the same on both sides of the equation.
How do you write ionic formulas?
1. Write the symbol and charge of the cation (metal) first and the anion (nonmetal) second. 2. Transpose only the number of the positive charge to become the subscript of the anion and the number only of the negative charge to become the subscript of the cation.
How do you write a net ionic equation if there is no precipitate?
Precipitation reactions are usually represented solely by net ionic equations. If all products are aqueous, a net ionic equation cannot be written because all ions are canceled out as spectator ions. Therefore, no precipitation reaction occurs.
Is charge conserved in a net ionic equation?
Note: charges in a net ionic equation are conserved. This means that the overall charge (called the net charge) on the reactants side (left) of the equation must equal to the net charge on the products side (right).
Why ionic reactions are fast?
It is not consumed or changed throughout the reaction. In general ionic bonds are formed faster than covalent bonds because in covalent compounds there has to be a bond breakage that will slow down the entire reaction, whereas in ionic bond it is more or less a substitution of ions.
What is the difference between molecular ionic and net ionic equations?
Molecular equations show species reacting as their molecular formula, with subscripts added to indicate their solid, liquid, gaseous, or aqueous nature. Ionic equations show species reacting as their ionic components. A net ionic equation is one in which spectator ions are removed.
What is an ionic equation explain with an example?
Explain giving an example. An equation which shows only the atoms and ions that actually take part is called an ionic equation. Such ions which remain as such and do not take part in the reaction are not indicated. Write a balanced chemical equation with state symbols for the following reactions.
