Properties
This chemical substance typically tastes bitter.
What is a base?
NaOH + HCl -->
What is NaCl + H2O ?
This lab technique is used to determine the concentration of an unknown substance
What is a titration?
What is pH = 4?
These bases dissociate completely in water
What is strong base?
Found in many fruits and vegetables.
What is acid?
HBr + LiOH -->
What is LiBr + H2O ?
This point in a titration is where [H+] = [OH-]
What is the equivalence point?
This [H+] corresponds to pH = 13
What is [H+] = 1.0 x 10-13M?
This is vinegar
What is a weak acid?
Makes OH-
What is a base?
H2SO4 + Mg(OH)2 -->
What is MgSO4 + H2O ?
This is used to determine the endpoint of a titration.
What is an indicator?
What is pH = 10?
This is the pH color change range of a strong acid/strong base titration
pH = 7
Reacts with metals to produce H2.
What is an acid?
HNO3 +Al(OH)3 -->
What is H2O + Al(NO3)3
Vinegar + NaOH --> NaC2H3O2 + H2O
This [Vinegar] corresponds to 38 mL of 0.3M NaOH and 15 mL of vinegar.
What is 0.76M vinegar?
This [OH-] corresponds to [H+] = 2.3 x 10-7M
What is 4.35 x 10-8M?
These are the six strong bases.
What are NaOH, RbOH, Ba(OH)2, CsOH, KOH, Sr(OH)2?
Electrolyte.
What is both acid and base?
Ca(s) + HCl -->

This is the number of moles of base present after 47 mL of 0.5M KOH have been titrated.
What is 0.0235 moles KOH?
This pH corresponds to 3.0 grams of HCl dissolved in 1 L of water.
These are the six strong acids.
What are HCl, HBr, HI, HNO3, H2SO4, HClO4?
