- What is a solute
- substance dissolved into the solvent or the substance present in the lesser amount
- factors that effect solubility
- Stirring-increases the movement of solute particles towards the solvent surface area-more solute particles are in contact with the solvent Temperature-heating speeds up the particles(for most solutes) If the solute is in gas phase the factors that affect solubility are opposite it
- can two gasses form a solution
- yes ar is an example(nitrogen and oxygen)
- Temp increases solubility except for NH3 this is because t is in gas phase
- -
- Dilute
- A small amount of solute dissolved in a large amount of solvent
- solubility
- amount of solute that will dissolve in a given quantity of 2g of zn/100ml of NaOH
- alloy
- when two solids form a solution
- supersaturated solurion
- When there is more dissolved solute than the solvent should be able to hold
- anti freeze is a solution of ethylene glycol and water
- -
- KI
- Potassium iodide
- KNO3
- Potassium nitrate
- Name some types of colloids
- fog-clouds,Smoke-smoke,foam-whip cream, emulsion-maynase-,sol- plint,gel-butter,gello
- What s a true solution
- A true solution is a homogeneous mixture. It cannot be seperated by filtering. The particles will not settle out.Solutions are transparent. Particles in a solution are not physically combines.
- What is it sad to be called when two liquids form a solution
- soluble or miscible
- NA4CI
- Ammonia Chloride
- What is a suspension
- a heterogeneous mixture is where the solute particles are fine, very large and can be seen without a microscope.They are temporarley hanging in the solvent and will eventually settle out.
- What is the most common solvent(universal solvent)
- water
- NACL
- Sodiu chloride
- NH3
- ammonia
- concentrated
- a large amount of solute dissolved in a small amount of solvent
- KCIO3
- Potassium chlorate
- NaNO3
- sodium nitrate
- saturated
- a solution contains as much dissolved solute it can possibly hold
- KCI
- Potaassium chloride
- two examples of an alloy
- brass and stainless steel
- dissociation
- solutions formed this way when the solvent(usually water)surround the solute.
- factors that affect solubility
- temp and type of solute
- What is a colloid(collodal suspension)
- A homogeneous mixture is where the solute particles are larger than a soluton but smaller than a suspension. The particles cannot be seen with microscope.The solute particles will not settle out. They are constantly bombarded by solvent particles that will also scatter a beam of light."search light"
- What is a solvent
- the part of the solution something gets dissolved in or the substance present in the greater aount
- unsaturated
- a solution that can dissolve more solute
