What is aqueous acid-base titration?
An acid-base titration is an experimental procedure used to determined the unknown concentration of an acid or base by precisely neutralizing it with an acid or base of known concentration. This lets us quantitatively analyze the concentration of the unknown solution.
What is mean by non aqueous titration?
Non aqueous titration refers to a type of titration in which the analyte substance is dissolved in a solvent which does not contain water.
What is the difference between aqueous and non aqueous solution?
An aqueous solution is a solution in which water is the solvent. A non-aqueous solution is a solution in which water is not the solvent. Examples of non-aqueous solutions are solutions used in dry cleaning (a solution of ethene in the solvent dichloromethane).
What is the aim of titration?
The purpose of titration is to determine an unknown concentration in a sample using an analytical method.
What is meant by Levelling effect?
Leveling effect or solvent leveling refers to the effect of solvent on the properties of acids and bases. The strength of a strong acid is limited (“leveled”) by the basicity of the solvent. Similarly the strength of a strong base is leveled by the acidity of the solvent. In water, OH− is the strongest base.
Why non aqueous titration is required?
The need for non-aqueous titration arises because water can behave as a weak base and a weak acid as well, and can hence compete in proton acceptance or proton donation with other weak acids and bases dissolved in it.
What are pM indicators?
A complexometric indicator is an ionochromic dye that undergoes a definite color change in presence of specific metal ions. Complexometric indicators are also known as pM indicators.
What is the principle of KF titration?
The principle of Karl Fischer titration is based on the oxidation reaction between iodine and sulphur dioxide. Water reacts with iodine and sulphur dioxide to form sulphur trioxide and hydrogen iodide. An endpoint is reached when all the water is consumed.
