Acid/Base Practice
1. Using the Arrhenius definitions, identify the following as acids, bases or salts by checking the appropriate column. Also,
if it is an acid, determine if it is monoprotic, diprotic or triprotic.
Substance
Base
Salt
Acid
Monoprotic Diprotic
Triprotic
HC2H3O2
Ca(OH)2
Mg(NO3)2
CoCl6
H3PO3
H2 S
Al(OH)3
HF
Zn(C2H3O2)2
KOH
2. Name the following Arrhenius acids.
A. HCl _______________________
B. HC2H3O2 _________________
C. H2SO4 _____________________
D. HNO3 ____________________
3. Using the bronsted – lowry definitions, label each member of the following equations as an acid, base, conjugate acid,
conjugate base. Remember the acid and base are on the reactant side and the conjugate acid and conjugate base are on the
product side.
A.
CH3COOH + H2O  H3O+ + CH3COO –
B.
F - + H2 O 
C.
H2 O
+ HOBr
D.
H2 O
+ HS -  H2S
E.
HNO3 + HPO4 –2
OH
+ HF
OBr-
+ H 3 O+
+ OH-
 NO3- + H2PO4 –
4. Use the bronsted-lowry definition to predict the conjugate acid to the following bases. Remember according to bronstedlowry, a base accepts an H+, so to get the conjugate acid, you must add an H to the formula and one to the overall charge.
A. NH3 _______________
B. HSO4- ______________
D. ClO- _______________
E. PO4-3 ______________
C. H2O ____________
5. Use the bronsted - lowry definitions to predict the conjugate base to the following acids. Remember that according to
bronsted-lowry, an acid is an H+ donor. So to get the conjugate base, you must remove an H from the formula and one from
the overall charge.
A. NH4+ _______________
B. H2O _______________
D. HCO3- _____________
E. H2C2O4 ____________
C. HClO4 ______________
6. Write in “A” for Acid or “B” for Base for each of the following: Be careful, some description may apply to both acids
and bases.
_____ 1. Solutions of these are electrolytes
_____ 2. Bitter taste
_____ 3. Turn red litmus to blue
_____ 4. Found in fruits and veggies
_____ 5. Produce H+ ions in solution
_____ 6. React with acids to produce salts and water
_____ 7. Turn phenolphthalein red
_____ 8. Sour taste
_____ 9. Feel slippery
_____ 10. NaOH
_____ 11. Found in cleaning products
_____ 12. Antacids
_____ 13. H3PO4
_____ 14. React with Active Metals to produce hydrogen gas
_____ 15. Produce OH- ions in solution
_____ 16. Dissociate in aqueous solutions
_____ 17. Al(OH)3
_____ 18. HCl
7. Review over your reaction types (synthesis, decomposition, combustions, single replacement and double replacement).
Use the pattern for double replacement to predict the products of an Arrhenius acid with and Arrhenius base.
