Solubility
Define solubility
What is the ability of a substance, (solute), to dissolve in a solvent
What is a mixture?
What are the physical combination of two or more pure substances (at least two different parts)
What happens when I combine a solute and a solvent?
You get a solution.
Name something that is soluble in water
What is salt, sugar, ect....
What is the definition of dissolve?
What is to mix completely ie. the solute dissolves into the solvent
Name something that is insoluble in water
What is oil, plastic, pepper, ect.
What does homogeneous mean?
Has no visible components/parts i.e. One substance is dissolved in another with parts being evenly mixed. Appears the same throughout.
What are two ways that we can describe concentration? Hint: Both terms start with a Q
What is qualitatively and quantitatively
What is one of the principals in the Particle Theory of Matter
What is:
All matter is made up of tiny particles.
These particles are always moving… they have energy
There are spaces between these particles
There are attractive forces between the particles
The particles of one substance differ from the particles of another
What are the 3 factors that affect solubility?
What are:
Surface area of the solute
Temperature
Pressure
What is a heterogeneous mixture?
Has visible components/parts, with parts not evenly mixed. You can see the individual parts.
Hydrogen peroxide is used to disinfect cuts. Hydrogen peroxide is a solution of 3% hydrogen and 97% water. What are the solute and the solvent?
What is hydrogen is the solute and water is the solvent
Using the particle theory of matter, what makes some things soluble and other things insoluble with a solvent
There are attractive forces between the particles
Give an example of a homogeneous mixture that is not a liquid.
What is Steel, Brass, Air, ect...
If something is concentrated, does that mean that it is also saturated? Why or why not?
No. Concentration is a spectrum based on various factors.
