What is an ionic equation

What is an ionic equation give an example?

(i) Solutions of barium chloride and sodium sulphate in water react to give insoluble barium sulphate and the solution of sodium chloride. (ii) Sodium hydroxide solution (in water) reacts with hydrochloric acid solution (in water) to produce sodium chloride solution and water.

What is an ionic equation GCSE?

A balanced ionic equation shows the reacting ions in a chemical reaction. These equations can be used to represent what happens in precipitation reactions .

What is a total ionic equation?

Summary. A net ionic equation shows only the chemical species that are involved in a reaction, while a complete ionic equation also includes the spectator ions. Identify and cancel out the spectator ions (the ions that appear on both sides of the equation).

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 a balanced complete ionic equation?

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. Balancing by charge means making sure that the overall charge is the same on both sides of the equation.

How do you write a balanced equation?

Balanced chemical equation: A chemical equation in which the number of each type of atom is equal on the two sides of the equation. Subscripts: Part of the chemical formulas of the reactants and products that indicate the number of atoms of the preceding element.

How do you balance a chemical equation?

Balance charge. Add e (electrons) to one side of each half-reaction to balance charge. You may need to multiply the electrons by the two half-reactions to get the charge to balance out. It’s fine to change coefficients as long as you change them on both sides of the equation.

What is the meaning of ion?

an electrically charged atom or group of atoms formed by the loss or gain of one or more electrons, as a cation (positive ion ), which is created by electron loss and is attracted to the cathode in electrolysis, or as an anion (negative ion ), which is created by an electron gain and is attracted to the anode.
