What is a homogeneous mixture containing a solute and solvent called?
Solutions are homogeneous mixtures containing two or more substances called the solute and solvent. The solute is the substance that dissolves. The solvent is the dissolving medium.
What is a mixture in which a fine powder does not dissolve but separates out to form a sediment?
Suspension. A mixture in which a fine powder does not dissolve but separates out to form a sediment. Concentrated. A solution is said to be called this if there is a lot of solute dissolved in the solvent.
What type of mixture separates upon standing?
suspension
A suspension is a heterogeneous mixture in which some of the particles settle out of the mixture upon standing.
What is the name of a mixture containing particles that are too small to be seen easily but are large enough to scatter a light beam?
Acids, Bases, and Solutions
| Question | Answer |
|---|---|
| A mixture containing particles that are too small to be seen easily but are large enough to scatter a light beam is called a | colloid |
| Neutralization is a reaction between an | acid and a base |
| You can find the pH of a substance by using | litmus indicator |
Is soda a homogeneous mixture?
For example, an unopened soda in a bottle has a uniform composition and is a homogeneous mixture. Once you open the bottle, bubbles appear in the liquid. The bubbles from carbonation are gasses, while the majority of the soda is liquid. An opened can of soda is an example of a heterogeneous mixture.
Can all mixtures be separated by physical processes?
Mixtures can be separated into pure substances by physical methods. Pure substances can be divided into two groups – elements and compounds. Elements are the simplest forms of matter and therefore cannot be broken down into simpler substances by any chemical or physical means.
What are the types of colloids and examples?
Examples of Colloids
| Class of Colloid | Dispersed Phase | Examples |
|---|---|---|
| Solid aerosol | solid | smoke, dust in air |
| Solid emulsion | liquid | cheese, butter |
| Liquid emulsion | liquid | milk, mayonnaise |
| Liquid aerosol | liquid | fog, mist, clouds, aerosol spray |
How can a substance be separated from a mixture?
Each substance is easily separated from the mixture: It can only be separated into its elements using chemical reactions: Examples: Air, sea water, most rocks
How are the particles of a suspension separated?
So a suspension can be separated by filtration. The suspension is unstable. The particles of a suspension settle down after some time. A suspension scatters a beam of light passing through it because of its large particle size.
Which is an example of a mixture of particles?
Particles range from individual atoms right up to particles that are big enough to see, like grains of sand. A mixture is made from different substances that are not chemically joined. For example, powdered iron and powdered sulfur mixed together makes a mixture of iron and sulfur.
Can a liquid be separated by centrifugation or filtration?
Sometimes, the solid particles in a liquid are minute enough to pass through a filter paper. In such cases, filtration cannot be used for separation. Such mixtures are separated by centrifugation.
