Q

AMPHIPROTIC EXAMPLE:

A

NaHCO3 IS A BASE BUT IT DOES HAVE THE ABILITY TO DONATE (ACID) OR ACCEPT (BASE) H+ DEPENDING ON CONDITIONS

17
Q

WHAT DOES NEUTRALIZATION MEAN:

A

WHEN H+ CANCEL OUT OH-

18
Q

NEUTRALIZATION DOES NOT MEAN _____

A

NEUTRAL

19
Q

WHAT IS THE EQUATION FOR FINDING THE [H+] AND [OH-]

A

KW = [H+][OH-] = 1 X 10^-14

20
Q

WHEN [H+} ______, [OH-] ______

A

INCREASES, DECREASES

21
Q

MOLARITIES TELL US ____ AND _____

A

[H+], [OH-]

22
Q

0.1M HCl equals how much [H+]

A

0.1

23
Q

HOW WOULD YOU FIGURE OUT THE [OH-] FROM THE EQUATION?

A

YOU WOULD FIGURE OUT THE [H+] FIRST

THEN DO 1 X 10^-14 DIVIDED BY THE ANSWER YOU GOT FROM THE [H+]

24
Q

[H+] TELLS US _____

A

pH

25
Q

WHAT IS THE EQUATION FOR pH?

A

pH = -LOG [H+]

26
Q

HOW DO YOU KNOW IF YOU ARE DOING THE pH EQUATION RIGHT?

A

IF IT IS AN ACID, THE ANSWER SHOULD BE LOW BECAUSE ACIDS HAVE LOW pH

IF IT IS A BASE, THE ANSWER SHOULD BE HIGH BECAUSE BASES HAVE HIGH pH

27
Q

IF YOU KNOW pH, YOU KNOW _____

A

[H+]

28
Q

WHAT IS THE EQUATION TO FIND [H+] WHEN YOU KNOW THE pH?

A

[H+] = 10^-pH

29
Q

HOW WOULD YOU PUT THE EQUATION IN IF YOU AJKFNJSM

A
