Science Homework

What's up with your face?

Objective One

The magic of solutions, colloids, and suspensions:
All three are mixtures.
Solutions have small particles that will never settle out, even if you sit there watching them for a million years.
Colloids have larger particles than solutions, and they will settle out eventually.
Suspensions have the largest particles of all three and settle out quickly to create an ugly muck.

When a solutions forms, the particles in the solute are surrounded by the particles of the solvent. (Like a gang and their wimpy victim.)

The solute raises the solvent’s boiling point and lowers its freezing point.

Have you made a solution or solution or suspension?  You basically have a fifty percent chance of being right.  But in the same way, it’s only one-third of a chance.  Well, I believe it is a solution for the simple fact that the food coloring does not settle out immediately.  Also, food coloring is mostly water.

Oh my gosh, I already answered this question!  Please check number three of this objective for my epic answer.

Objective Two

Concentration is measured by measuring how much of one substance is mixed with another substance.  If you’re a magical fairy, though, you can use your magical fairy powers to measure concentration.

“You can identify a substance by its solubility because it is a characteristic property of matter.” (http://wiki.answers.com/Q/Why_is_solubility_useful_in_identifying_substances)

The factors that affect the solubility of a substance are . . . . . . pressure, temperature, the solvent, and the trajectory of the sun and the moon on the night of—never mind.

Temperature affects the solubility because heat increases solubility.

Solubility is a property of matter . . . just like INERTIA!

Objective Three

Four properties of acids are:
they taste sour
they end in the suffix –ic
they create a hydrogen ion when put into a solution
and it turns litmus paper “red”.

Four properties of bases:
first base, second base . . . just kidding.
are slippery
are bitter
turn litmus paper “blue”
and usually end in the suffix –ide.

You can use litmus paper to distinguish an acid from a base because acids turn litmus paper “red” and bases turn litmus paper “blue”.

A food contains acid in its ingredients if it is sour.

Fertilizers are bases, and they can irritate your skin.  (Plus, the universe is out to kill us, so whenever we can be cautious, we must take that chance.)

Objective Four

The ion found in acids is . . . . drum roll, please . . . . . HYDROGEN!  Haha.  Watch me get that WRONG!

As with every other thing, acids form a hydrogen ion, and bases form a . . . . whatcha-ma-callit ion.

A substance’s pH tells you how acidic or . . . . basic a substance is.

A substance of pH 6 would contain fewer because 6 is closer to the neutral 7 than 3.

Objective Five

For people who have lost their teeth, the digestive process is slower because the acids have to eat away at unchewed food which takes longer.

Objective Six

acid – “any of various typically water-soluble and sour compounds that in solution are capable of reacting with a base to form a salt, redden litmus, and have a pH less than 7, that are hydrogen-containing molecules or ions able to give up a proton to a base, or that are substances able to accept an unshared pair of electrons from a base”(http://www.merriam-webster.com/dictionary/acid?show=1&t=1291247367)

neutralization – the process of an acid or a base gaining a pH of 7 . . . . becoming neither an acid or base

indicator – “a substance (as litmus) used to show visually (as by change of color) the condition of a solution with respect to the presence of a particular material (as a free acid or alkali)”
(http://www.merriam-webster.com/dictionary/indicator)

corrosive – characterized by eating away at some metals

hydroxide ion – hydrogen with one more electron than usual, negative
