Is the sand and water considered a mixture or a
solution?
Mixture—not the same throughtout. Parts can be be physically separated
b/c they are not chemically changed.

When substances in a solution are in the same physical state (solid, liquid, gas), which is the solvent?
The solvent is the substance that is present in the
greatest amount. Given that information...what would the
solvent be for the air we breathe? NITROGEN!

Please name at least TWO examplesof common household bases.
Drain cleaner, soap, ammonia, alkaseltzers, baking soda,
detergent, acetone (high levels)

True or False. Numbers below 7 on the pH scale indicate basic
solutions.
False—it would indicate an acidic solution

Please explain the concept of neutralization and provide a
real-life example of this.
Neutralization: a chemical reaction in which an acid reacts with a base to
form salt. A common example occurs when you swallow an antacid tablet to
relieve an upset stomach.

being neutral!)
