Topic 10: Acids, Bases, and Salts

Question 1

Arrhenius Theory

Answer 1

Acids:
yield H+ or H30+ ions
yield only POS ions in solution

Bases:
yield OH- ions
yield only NEG ions in solution

-Acids and bases are electrolytes

Question 2

Elecrolytes

Answer 2

substance when dissolved in H20 is capable of conducting electricity

Question 3

Neutralization reactions

Answer 3

Arrhenius acid and base react to form salt and water

Question 4

A theory that is not Arrhenius states

Answer 4

Acid: H+ doner
Base: H+ acceptor

Question 5

Titration

Answer 5

lab process where VOLUME of a solution is used to determine the CONCENTRATION of another

Question 6

pH

Answer 6

a measure of the acidity/alkalinity of a solution
lower pH=more acidic

Question 7

what does lower and higher pH mean for concentration

Answer 7

LOWER:
higher conc. of acid
lower conc. of base

HIGHER:
lower conc. of acid
higher conc. of base

Question 8

a neutral pH is at which number on the pH scale?

Answer 8

7
it means there’s an equal concentration of acid and base
ex: water

Question 9

one pH unit DECREASE is equal to..

Answer 9

tenfold (x10) INCREASE in acid concentration

Question 10

one pH unit INCREASE is equal to…

Answer 10

tenfold (x10) DECREASE in acid concentration
