SOLUTION AND RATE OF SOLUBILITY

Sugar water is example of

• solvent

• solute

• solution

• suspension

Examples of solute are

• water

• salt

• flour

• orange juice

(a)   is a clear mixture formed when a solute dissolves in a solvent.

_____________ is a cloudy mixture formed from undissolved solute particles in a solvent.

• Solution

• Suspension

• Organic solvent

What is the type of solution found in the Dead Sea?

(a)  

Why there is no residue left when a solution is filtered?

A suspension appears ___________ as the solute particles do not dissolve in the solvent.

• cloudy

• clearly

• dark

Solubility of a solute is the (a)   amount of the solute that can dissolve in 100 ml of solvent at a specific temperature.

Sugar dissolves faster in hot coffee when stirred. Why?

• Low temperature and rate of stirring of solvent cause the particles to move rapidly.

• High temperature and rate of stirring of solvent cause the particles to move rapidly.

• High temperature and rate of stirring of solvent cause the particles to move slowly.

Why fine sugar dissolves faster compared to sugar cubes?

• The bigger the size of solute, the bigger the total surface area that is exposed to the solvent particles

• The smaller the size of solute, the smaller the total surface area that is exposed to the solvent particles

• The smaller the size of solute, the bigger the total surface area that is exposed to the solvent particles
