This document defines and describes mixtures and solutions. It explains that mixtures are made of two or more substances physically mixed together and can be either heterogeneous, with visible particles of different substances, or homogeneous, appearing uniform throughout. Solutions are defined as homogeneous mixtures formed when one substance dissolves in another, and key terms like solute, solvent, solubility, soluble, and insoluble are introduced in relation to solutions. Dilute and concentrated solutions are also defined based on the relative amounts of solute and solvent.
solution, in chemistry, a homogenous mixture of two or more substances in relative amounts that can be varied continuously up to what is called the limit of solubility. The term solution is commonly applied to the liquid state of matter, but solutions of gases and solids are possible. Air, for example, is a solution consisting chiefly of oxygen and nitrogen with trace amounts of several other gases, and brass is a solution composed of copper and zinc.
A brief treatment of solutions follows. For full treatment, see liquid: Solutions and solubilities.

MATTER
Mixture
It is composed of two or more pure substances combined through physical means in varying proportions.
Each pure substance in a mixture retains its property.
The components of a mixture can be separated by physical means depending on the states of the pure substances in a mixture.
It can be classified into two namely homogeneous and heterogeneous mixtures.
Homogeneous Mixture
It has uniform composition and properties.
It has only one phase in which it is hard to determine the components of the mixture visually.
Heterogeneous Mixture
It has varying composition and properties.
It may have two or more phases since the individual substance is visually distinct
Solution, Suspension and Colloid
Mixtures can also be classified based on particle size namely solution, suspension, and colloid.
A solution is a homogeneous mixture while a suspension and a colloid are heterogeneous mixtures.
1. Solution
It has two or more substances uniformly dispersed throughout the mixture. It forms a single phase
It has the smallest particle size. Particles of a solution are invisible to the naked eye.
2. Suspension
The components of a suspension separate over time due to the influence of gravity.
It has the largest particle size compared to the other types of mixtures. The particles in a suspension are visible to the naked eye
3. Colloid
The particles in a colloid only remain suspended in the medium when viewed using a microscope.
It has an intermediate particle size compared to solutions and suspensions. The particles appear to be invisible to the naked eye.
Tyndall Effect
Colloidal particles exhibit Brownian movement and cause Tyndall effect.
Brownian movement is the random movement of particles suspended in gas or liquid.
This random motion of particles causes the scattering of light or Tyndall effect. Tyndall effect is usually demonstrated by passing a ray of light through a sample mixture.
Tyndall effect could be used to identify the mixture as solution, colloid, or suspension.

Synthetic fibers play a crucial role in modern society, impacting various aspects of daily life, industry, and the environment. ynthetic fibers are integral to modern life, offering a range of benefits from cost-effectiveness and versatility to innovative applications and performance characteristics. While they pose environmental challenges, ongoing research and development aim to create more sustainable and eco-friendly alternatives. Understanding the importance of synthetic fibers helps in appreciating their role in the economy, industry, and daily life, while also emphasizing the need for sustainable practices and innovation.
2024.06.01 Introducing a competency framework for languag learning materials ...Sandy Millin
http://sandymillin.wordpress.com/iateflwebinar2024
Published classroom materials form the basis of syllabuses, drive teacher professional development, and have a potentially huge influence on learners, teachers and education systems. All teachers also create their own materials, whether a few sentences on a blackboard, a highly-structured fully-realised online course, or anything in between. Despite this, the knowledge and skills needed to create effective language learning materials are rarely part of teacher training, and are mostly learnt by trial and error.
Knowledge and skills frameworks, generally called competency frameworks, for ELT teachers, trainers and managers have existed for a few years now. However, until I created one for my MA dissertation, there wasn’t one drawing together what we need to know and do to be able to effectively produce language learning materials.
This webinar will introduce you to my framework, highlighting the key competencies I identified from my research. It will also show how anybody involved in language teaching (any language, not just English!), teacher training, managing schools or developing language learning materials can benefit from using the framework.
1. MIXTURES
• Matter that can be made up of 2 or
more substances PHYSICALLY mixed
together.
• The substances that make up a
mixture can be present in any amount.
• Can be separated by PHYSICAL
means
2. 2 KINDS OF MIXTURES:
• HETEROGENEOUS MIXTURES
– DO NOT APPEAR THE “SAME”
THROUGHOUT
– “LEAST MIXED”
– PARTICLES ARE LARGE
ENOUGH TO BE SEEN
3. • HOMOGENEOUS MIXTURES
– Appear to be the same
throughout
– “Well Mixed”
– Particles are very small--can’t
be seen
4. SOLUTIONS
• A type of homogeneous mixture
formed when one substance
dissolves in another
• “Best Mixed” of all mixtures
5. SOLUBILITY
• SOLUTE: The substance that is
dissolved in a solution
• SOLVENT: The substance that does
the dissolving in a solution
– Water is the most common solvent
– Water is the “UNIVERSAL
SOLVENT”, since it can dissolve
many substances
6. • SOLUBILITY: The amount of a solute
that can be dissolved in a given amount of
solvent
• SOLUBLE: Term that describes a
substance that dissolves in another
substance
• INSOLUBLE: Term that describes a
substance that does not dissolve (or very
little dissolves) in another substance
7. TYPES OF SOLUTIONS
• DILUTE SOLUTION
– A solution in which a little amount
of solute is dissolved in a large
amount of solvent.
• CONCENTRATED SOLUTION
– A solution in which a lot of solute
is dissolved in a small amount of
solvent.
