Answer 1

Acid

Question 2

A molecule that accepts H+ ion

Answer 2

Base

Question 3

Adding water to a solution in order to decrease the concentration

Answer 3

Dilution

Question 4

A substance that turns one color in the presence of acid and another color in the presence of bases

Answer 4

Indicator

Answer 5

Salt

Question 6

The process of slowly reacting a base of unknown concentration with an acid of known concentration until just enough acid has been added to react with all the base. This process determines the concentration of an unknown base.

Answer 6

Tritiation

Question 7

compounds that can act either as an acid or base, depending on the situation.

Answer 7

Amphiprotic compounds

Question 8

Another name for amphiprotic compounds.

Answer 8

Amphoteric compounds

Question 9

The point in a titration where the acid and base have completely reacted with one another. It is usually accompanied by an indicator’s change in color.

Answer 9

Endpoint of the titration

Question 10

H30+

Answer 10

Hydronium ion

Question 11

The number of moles of solute per kilogram of solvent

Answer 11

Molality (m)

Question 12

A concentration unit that tells us how many moles of a substance are in a liter of solution. It is determined by taking the number of moles of a substance and dividing by the number of liters of solution.

Answer 12

Molarity (M)

Question 13

A reaction between acid and base that neutralizes both, typically forming salt and water.

Answer 13

Neutralization reaction

Question 14

Gram equivalent weight/liters of solution

Answer 14

Normality

Question 15

An acid that can donate more than one H+ ion

Answer 15

Polyprotic acid

Question 16

Another name for a base: Bases accept H+ ions, which are protons

Answer 16

Proton acceptor

Question 17

Another name for an acid: Acids donate H+ ions which are protons

Answer 17

Proton donor

Question 18

Ions not involved in a reaction

Answer 18

Spectator ions
