3.0 x 10 -4 M? What is the Ka? (ionization constant)
What volume of .10 M HCl is needed to neutralize 10. mL of .30 M Ca(OH)2?
What is the molarity of an HCl solution if it takes 5.0 mL of .20 M NaOH solution to neutralize 8.0 mL of the HCl?
Proton (H+) acceptor
strong base –readily accepts a proton- large Kb
weak base – does not readily accept a proton- small Kb
