CBSE Chemistry Project Report for School Students.
Chemistry Project Report Experiment Acid and Bases
Types of Fabrics :
Depending upon the sources, the various
types of fibres can be classified
into the following three main categories :
(i) Animal fibres e.g. Wool & Silk.
(ii) Vegetable Fibres e.g. Cotton & Linen.
(iii) Synthetic Fibres e.g. Nylon & Polyester.
Besides their chemical composition and properties, most important property of
these fibres is their tensile strength.
Tensile strength mean the extent to
which a fibre can be stretched without breaking and it is measured in terms of
minimum weight required to break the fibre. To determine the tensile
strength of any fibre, it is tied to a hook at one end and weighted are slowly
added to the other end until the fibre break.
Chemistry Project Report Adsorption
Definition of Adsorption : The phenomenon of attracting
and retaining the molecules of a substance on the surface of a liquid or a solid
resulting in the higher concentration of the molecules on the surface is called
Adsorption.
The substance thus adsorbed on surface is called Adsorbate and the substance
on which it is adsorbed is called Adsorbent.
Causes of Adsorption
Adsorption arises at the surface of solids as a result of presence of
unbalanced forces at the surface. These forces develop either during the
crystallization of solids or by virtue of the presence of unpaired e- in
d-orbital.
Chemistry Project Report on Cells
Introduction :
What is Cells : Although every spontaneous redox
reaction can be used as the basis of an electrochemical cell, yet every such
electrochemical cell is not suitable for purpose. This is because of the
following two reasons :-
(i) Electrochemical cells using salt bridges have high internal resistance.
As a result, if we try to draw large current from them, their voltage drops
sharply.
(ii) They lack the compactness and ruggedness for portability.
Types of cells
(a) Primary Cells.
(b) Secondary Cells.
(c) Fuel Cells.
Constituents of An Alloy Chemistry Project Report
An Alloy is a homogenous mixture of two or more metals or a non-metal.
An alloy of mercury with another metal is called amalgam.
Alloys are usually harder than their components but very often less ductile
and less malleable. Thus the hardness of gold is increased by addition of copper
to it. The melting point of an alloy is always lower than the melting points of
the constituent metals.
In this project report, you find Experiment on Constituents of an alloy,
Preparation of Alloys, Analysis of an alloy, To analyze a sample of brass
qualitatively, bronze qualitatively, duralumin qualitatively, Uses of alloys,
uses with modify chemical reactivity, To increase hardness, To increase
tensile strength, To lower the melting point, To modify the colour and resist
corrosion.
