Performance in General Chemistry Submitted By: Roxane Rosendo (12-TELFORD)

The document outlines an experiment on mixtures in general chemistry, detailing the solute and solvent for various combinations, such as sugar and salt in water. It describes the number of phases observed in each mixture and identifies which mixtures are solutions. The conclusion emphasizes that solutions can involve different phases of matter and result in a homogeneous mixture.

PERFORMANCE IN GENERAL CHEMISTRY

Submitted by: Roxane Rosendo (12-TELFORD)

Question:

1.    Describe the mixture that resulted after mixing. Write your answer in column 3.

2.    How many phases do you observe? Write your observation in column 4.

3.    Identify the solute in each of the mixture. Write your answer in the blank.

 Sugar in Water - Sugar is the solute


 Salt in Water - Salt
 Mongo seeds in Water - Mongo seeds, but it could not be dissolved
 Powdered Juice in Water - Powdered Juice
 Cooking Oil in Water - Cooking oil could be miscible with organic solvent
 Vinegar in Water-  Vinegar the solute is acetic acid

4. What is the solvent in each mixture?

 The solvent in each mixture is water because this is the one I used to dissolve the
substances.

5.Which of the following are solutions? Write your answer in column 5

Number of
phases
Sample solid or Will dissolve in Appearance Solution or not?
liquid one cup of
water

(yes or No)
Sugar Yes The sugar has dissolved into the water,  2 Phases SOLUTION
but it remains in the water even though
we can no longer see it. The heat from
the water broke up the crystals into so
small fragments that they "disappeared."
Because the water molecules have bound
to the sugar molecules, we can't see it
anymore.
Salt Yes Salt dissolves in water until the solution  1 Phase SOLUTION
reaches a saturation point. Excess salt will
not dissolve once the saturation point
has been reached, yit will remain visible
as salt grains. As water evaporates, salt or
other dissolved materials will revert to
their solid condition.
Mongo seeds No Monggo seeds are water insoluble, they  1 Phase NOT
remain solid and settle to the bottom of
the cup.
Powdered juice Yes It is simply dissolving powder into water  1 Phase SOLUTION
and allowing hydration waters to
surround it until it becomes a juice. That
is known as a homogeneous or uniform
mixture. The juice powder will be mixed
with the water.
Cooking oil No The cooking oil float on top of the  2 Phases NOT
water, forming an oily surface layer. I
think it is because oil is less dense than
water.
Vinegar No Vinegar is a polar substance, which  2 Phases NOT
means that its molecules are attracted to
water molecules called "hydrophilic". As a
result, it can be dissolved in water. It does
not dissolve technically, but rather forms
a homogeneous solution with water.

TABLE:

Conclusion:
Any of the phases of matter can be dissolved in another phase of a solution, which is a
uniform mixture of molecules. Whether they are solids, liquids, or gases. A solution is a liquid
that is a homogeneous mixture of two or more substances.They combine to form a single
phase, which is usually liquid. o In a process known as solution or dissolution, solvent particles
surround solute particles via electrostatic interactions.
