Conductometric titration is both the result and the process in which the reaction of an ionic solution is created because of its electrical conductivity. This is done through the loss or gain of ions between two solutions. Different ionic solutions such as acid-base or chemicals conduct electric currents differently when added to other solutions. The conductive properties, also known as the shift of ions between two of these solutions, result in what the solution is known to be. Conductometric titration determines the concentration of these solutions in relation to each other.

Conductometric Titration's Conductance of Ions

Conductometric titration is the process of adding an element to a base solution. The change of ions, or conductivity, changes the concentration of the substances. For example, if HCI is titrated with NaOH the conductivity of the solution decreases. The solution also changes. This happens because faster moving ions are replaced by slower moving ones. The equivalence point is breached and the conductivity decreases. The conductivity of saline is a good example because of its extreme relation between loss or gain of ions in the solutions it creates.

Conductometric Titration Formula

Conductometric titration is a mathematical formula that plots the conductivity, or the properties that change in a solution. It takes into account the volume of base being calculated and the added amount of titrate. Linear measurements are plotted on a graph to illustrate the process of titration.

Conductometric Acid-Base Titration

Conductometric acid-base titration uses an instrument called a burette. Like other methods of conductometric titration, a change in the relationship of electrical current, or ions, tells the relative concentration of two ionic solutions put together. The burette measures the two solutions until an equivalence point, when the two solutions become balanced. An indicator will change in colour at a specific PH. Conductometric titration as a definition or mathematical formula is then used to calculate the concentration.

Conductometric Redox Titration

Conductometric redox titration is a method of the electrical current, or ions of a solution, affecting the concentration of an unknown chemical. An example of conductometric redox titration is a percentage you may encounter in common chemical products. The percentage of hydrogen peroxide in a bottle is a type of conductometric titration because it is caused by the relationship of ions that have changed the concentration of one chemical to another.
