7
BASES ARE MORE THAN ____ ON pH
7
ACIDS BEGIN WITH _____
H
BASES END IN _____
OH
WHAT ARE STRONG ACIDS
COMPLETELY IONIZE TO GIVE ALL THEIR H+
WHAT ARE THE 4 STRONG ACIDS:
HCl
HClO4
HNO3
H2SO4
weak acids :
only give some H+
HOW DO WE KNOW IF AN ACID IS STRONG OR WEAK?
IF WE EAT IT , IT IS WEAK
IF WE DO NOT EAT IT, IT IS STRONG
A STRONG BASE:
GIVE ALL THEIR OH-
A WEAK BASE:
ONLY GIVE SOME OH-
STRONG BASE EXAMPLES:
NaOH
KOH
WEAK BASE EXAMPLE:
NH4OH
NaHCO3
CaCO3
Acid is the proton _____
donor
BASE IS THE PROTON _____
ACCEPTOR
AMPHIPROTIC DEFINITION:
CAN EITHER DONATE OR ACCEPT H+
AMPHIPROTIC EXAMPLE:
NaHCO3 IS A BASE BUT IT DOES HAVE THE ABILITY TO DONATE (ACID) OR ACCEPT (BASE) H+ DEPENDING ON CONDITIONS
WHAT DOES NEUTRALIZATION MEAN:
WHEN H+ CANCEL OUT OH-
NEUTRALIZATION DOES NOT MEAN _____
NEUTRAL
WHAT IS THE EQUATION FOR FINDING THE [H+] AND [OH-]
KW = [H+][OH-] = 1 X 10^-14
WHEN [H+} ______, [OH-] ______
INCREASES, DECREASES
MOLARITIES TELL US ____ AND _____
[H+], [OH-]
0.1M HCl equals how much [H+]
0.1
HOW WOULD YOU FIGURE OUT THE [OH-] FROM THE EQUATION?
YOU WOULD FIGURE OUT THE [H+] FIRST
THEN DO 1 X 10^-14 DIVIDED BY THE ANSWER YOU GOT FROM THE [H+]
[H+] TELLS US _____
pH
