What is the difference between equivalent point and end point in analytical chemistry?
The equivalence point is the point in a titration when the amount of added standard reagent is chemically equal to the amount of analyte.
The end point is the point in a titration when a physical change occurring immediate after the equivalence point
In analytical chemistry, an equivalent point is the point in a titration where the amount of titrant added is stoichiometrically equivalent to the amount of analyte present. The end point, on the other hand, is the point at which a color change or some other indicator signals that the reaction is complete. The end point may not always coincide with the equivalent point, depending on the nature of the reaction and the indicator used.
The stoichiometric point, of a chemical reaction occurs during a chemical titration when the amount of titrant added is equal, to the amount of analyte present in the sample, where as.
The end point (similar, but not the same as the stoichiometric point) refers to the point at which the indicator changes color in a colorimetric titration.
The endpoint is when the solution changes colour in a titration.
The equivalence point is the point at which exactly the same amount of titrant is added as the (stoechiometric) amount of analyte, present in the sample to be analysed.
If there is a steep, sudden increase in titration curve at that point then it can accurately be detected by an approprate indicator.
[The role of indicator is to show the endpoint as close as possible at the equivalence point]

Give the 5 principal of the brnches in chemistry?
The five main branches of chemistry are organic chemistry, inorganic chemistry, physical chemistry, analytical chemistry, and biochemistry. Each branch focuses on different aspects of matter and the interactions between substances. Organic chemistry studies carbon-based compounds, inorganic chemistry focuses on non-carbon compounds, physical chemistry examines the physical properties and behavior of matter, analytical chemistry involves identifying and quantifying substances, and biochemistry studies chemical processes in living organisms.
Are the boundaries between the five areas of chemistry firm?
The boundaries between the five areas of chemistry (organic, inorganic, physical, analytical, and biochemistry) are not rigid and often overlap. Many topics in chemistry can be studied from multiple perspectives, leading to collaboration and interdisciplinary research. Specialization within each area may vary depending on the research focus or application.
What is the difference between a molar solution and a normal solution?
A molar solution is a solution with a known concentration expressed in moles of solute per liter of solution, while a normal solution is a solution with a known concentration expressed as gram-equivalents of solute per liter of solution. Molar solutions are commonly used in chemistry, while normal solutions are used more in analytical chemistry and chemical analysis.
What are two branches of chemistry?
Chemistry is the branch of science that deals with the properties, composition and the structure of matter. It also deals with chemical reactions, changes in matter, and the principles which govern these changes. Lighting a fire, making ice cream, and riding in a hot air balloon all deal with chemistry.Below are the 6 MAIN Branches of chemistry... but there are many sub-branches1. Organic chemistry - the study of most carbon-containing compounds.2. Inorganic chemistry - the study of all substances not classified as organic, mainly those compounds that do not contain carbon.3. Physical chemistry - the study of the properties and changes of matter and their relation to energy.4. Analytical chemistry - the identification of the components and composition of materials.5. Biochemistry - the study of substances and processes occurring in living things.6. Theoretical chemistry - the use of mathematics and computers to understand the principles behind observed chemical behavior and to design and predict the properties of new compounds.Examples of sub-branches include geochemistry and electro-analytical chemistry.
Mass by difference?
Mass by difference is a method used in analytical chemistry to determine the mass of a component in a mixture by weighing the entire mixture before and after the component of interest is removed. The mass of the component is then calculated as the difference between the two measurements. This technique is commonly used when the component of interest cannot be easily separated or directly measured.
