## TERMS USED IN VOLUMETRIC ANALYSIS

### What is Titration?

When one of the solutions is taken in a conical flask and the other is added carefully from the burette till the chemical reaction between them is just complete, the process is called titration.

### What is Titrant?

The solution of known strength is called titrant.

### What is End Point or Equivalence Point?

It is the point at which the chemical reaction involved in the titration is just complete.

### What is an Indicator?

Any substance which indicates the endpoint of the titration (by change of color) is called an indicator.

### What is the Strength of a Solution?

The strength of a solution is the amount of the substance present in one liter of the solution..

### What is Normality?

Normality of a solution can be defined as the number of gram equivalents of solute dissolved in 1000ml of solution. It is represented by N. The gram equivalent of a substance is the number of grams of the substance chemically equivalent to one gram-atom of hydrogen in a given reaction.

### What is a Normal Solution?

The solution which contains one gm equivalent of the solute in one liter of the solution

### What is Molarity?

Molarity can be defined as the number of moles of solute dissolved in 1000ml of solution. We need two pieces of information to calculate the molarity of a solute in a solution:
The moles of solute are present in the solution.
The volume of solution (in liters) containing the solute.

### What is a Standard Solution?

A solution whose strength is known is called a standard solution.

### What is Error?

It is defined as the difference between an experimental value and the actual value of a quantity.

### What is Accuracy?

Accuracy is the term that refers to the correctness of measurement in comparison with the true or accepted value of the quantity measured. Accuracy is usually expressed in terms of error.

### What is Precision?

It is the degree of reproductively of a series of measurements on the same property.
Precision is the degree of reproductivity of a series of measurements on the same property. A significant figure is defined as the number which expresses the result of measurement such that only the last digit is in doubt.

### When Potassium Permanganate is Titrated?

Potassium permanganate is a chemical oxidant that can be used to determine the properties of substances by direct or indirect titration. Potassium Permanganate is used as an indicator.
Titrations must be carried out in a solution containing strong acid, such as hydrochloric or sulfuric.

Methyl Dopa

### What is Conductometric Titration?

Conductometric titration is a type of titration method in which the equivalence point is detected by measuring the conductivity of the solution. A conductometer is an instrument that measures the electrical resistance or conductance of a solution. Conductometry is the process of measuring this resistance or conductance. Conductometric titration can be used to determine total dissolved solids in water, concentrations of acids and bases, and also to detect metal ions.

### What is Non-aqueous Titration?

Non-aqueous titrations are titrations that do not use water as the solvent. These titrations are often used to measure the acidity or basicity of a solution.

### Which indicator is used in complexometric titration?

Fast Sulphon Black, Eriochrome Black T, Eriochrome Red B, Patton Reeder, or Murexide. Calcein with EDTA for calcium. Patton-Reeder Indicator with EDTA for calcium with magnesium.

### What is Molality?

It is defined as a number of moles of solute dissolved in 1 kilogram of solvent. Molality Moles of solute/ Mass of solvent in kilograms

### What is Mole Fraction?

The mole fraction, of a component in a solution, is the ratio of the number of moles of that component to the total number of moles of all components in the solution.

### What is Formality?

The formality of a solution may be defined as the number of gram formula masses of the ionic solute dissolved per liter of the solution. It is represented by F.

### What is Equivalent Weight?

The mass of a substance especially in grams that combines with or is chemically equivalent to eight grams of oxygen or one gram of hydrogen:ย the atomic or molecular weight divided by the valency.
