Acid and Base Identification

Fill in the blanks with capital letters, "A", "B", or "C" to identify the types of compounds fitting the descriptions.

Aacid (B) base (C) both
  1. can cause very severe burns to the skin.
  2. form electrolyte solutions in water when ionized.
  3. bitter taste.
  4. sour taste.
  5. releases hydrogen ions.
  6. have hydroxide ions.
  7. when combined, form water and salt.
  8. corrodes metals.
  9. has a pH from 1 to 6.9.
  10. has a pH from 7.1 to 14.
  11. HCl, HI, HNO3.
  12. LiOH, KOH, Mg(OH)2.

Verified Answer :

1.A  (when acids react with organic molecules on your skin the reaction is highly exothermic which is why it burns you)
2.C  (acids and bases can dissociate into ions or create ions)
3. B (bases tend to taste bitter an example being soap)
4.A (acids tend to taste sour an example being citric acid from lemons)
5.  A (the arrhenius acid definition is that acids dissociates into H⁺ ions)
6. B (the arrhenius base definition is that bases dissociate into OH⁻ ions)
7. C (Strong acid-strong base or weak acid-strong base reactions form water and salts) 
8.  A (I have heard that some metals can be corroded by some bases but I don't think bases usually corrode metal)
9.  A (acids have lower pH values with 7 being neutral)
10. B (bases have higher pH values with 7 being neutral)
11. A  (these are some of the strong acids)
12. B  (these are some of the strong bases)

I hope this helps.  Let me know if anything is unclear.
