Difference Between Molecular Equation and Ionic Equation
Table of Contents
ionic equation: An equation in which dissolved ionic compounds are shown as free ions. molecular equation: An equation in which the formulas of the compounds are written as though all substances exist as molecules.
What is a 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.
What is a molecular equation example?
1: The white silver chloride precipitate instantly forms when a solution of silver nitrate is added to a solution of sodium chloride. This is called a molecular equation. ... The example below shows the reaction of solid magnesium metal with aqueous silver nitrate to form aqueous magnesium nitrate and silver metal.
What are ionic equation explain giving an example?
An ionic equation is a chemical equation where the electrolytes in aqueous solution are written as dissociated ions. Example: 1) Sodium chloride(aq) + silver nitrate(aq) → silver chloride(s) + sodium nitrate(aq) >>Ag+(aq) + Cl-(aq) → AgCl(s) 2) Sodium(s) + hydrochloric acid(aq) -> sodium chloride(aq) + hydrogen(g).
How do you convert molecular equations to net ionic equations?
Write and balance the molecular equation first, making sure that all formulas are correct. Then write the ionic equation, showing all aqueous substances as ions. Carry through any coefficients. Finally, eliminate spectator ions and write the net ionic equation.
How do you write a complete ionic equation?
For any ionic compound that is aqueous, we will write the compound as separated ions.
What is the molecular formula?
A molecular equation is an equation in which the formulas of the compounds are written as though all substances exist as molecules. However, there is a better way to show what is happening in this reaction. ... A single-replacement reaction is one in which an element replaces another element in a compound.
How do you find the molecular formula?
Divide the molar mass of the compound by the empirical formula mass. The result should be a whole number or very close to a whole number. Multiply all the subscripts in the empirical formula by the whole number found in step 2. The result is the molecular formula.
What is an example of a net ionic equation?
This net ionic equation tells us that solid silver chloride is produced from dissolved Ag+start text, A, g, end text, start superscript, plus, end superscript and Cl−start text, C, l, end text, start superscript, minus, end superscript ions, regardless of the source of these ions.
Do you balance ionic equations?
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.
What is the ionic equation for Neutralisation?
A salt is a neutral ionic compound. Let's see how a neutralization reaction produces both water and a salt, using as an example the reaction between solutions of hydrochloric acid and sodium hydroxide. The overall equation for this reaction is: NaOH + HCl → H2O and NaCl.
