BIOCHEM CHAPTER 10 EXAM 10
Arrhenius acid (electrolyte) - CORRECT ANSWER-Produces H+ ions when dissolved in
water. Sour taste and turn blue litmus red

Name for H+ acid and nonmetal ions? - CORRECT ANSWER-Prefix hydro and end with
ic acid

Name for H+ and polyatomic ions? - CORRECT ANSWER-Change end of name from
ate to ic acid or ite to ous acid

Only exception for acid names? - CORRECT ANSWER-HCN

Arrhenius base (electrolyte) - CORRECT ANSWER-Produces OH- ions when dissolved
in water. Taste bitter, slippery, and turn litmus blue and pheno pink.

Naming bases? - CORRECT ANSWER-Hydroxide at end

Brønsted-Lowry acid/base theory - CORRECT ANSWER-Acid is a substance that
donates H+, base accepts H+

Conjugate - CORRECT ANSWER-Pairs of molecules that differ by one H+

Strong acid - CORRECT ANSWER-completely ionizes in solution, dissociates into ions
100%(strong electrolytes). Have weak conjugate bases

Weak acid - CORRECT ANSWER-dissociates only slightly in water to form a few ions in
aqueous solutions (weak electrolytes) Strong conjugate bases

6 common strong acids - CORRECT ANSWER-HCl, H2SO4, HNO3, H3PO4,
HC2H3O2, H2CO3

Strong Base - CORRECT ANSWER-Strong electrolytes formed from metals of group
1A and 2A (hydroxides)

Weak Base - CORRECT ANSWER-weak electrolytes (NH3 aka ammonia)

Equilibrium symbol - CORRECT ANSWER-Two arrows on top of each other

Equilibrium - CORRECT ANSWER-Reversible reaction that moves in forward and
reverse directions . Reached when there are Bo further changes in concentration. Rate
of forward is = rate of reverse
