IONS IN SOLUTION TAKS QUESTIONS
July 2004 – 11:
(18) In this apparatus, the seawater is an example of a —
F* strong electrolyte
G weak acid
H nonelectrolyte
J strong base
Spring 2003 – 11:
(33) Two clear solutions are placed in separate beakers. The first solution has a pH of 4,
and the pH of the second solution is unknown. If the two solutions are mixed and the
resulting pH is 5, the second solution must have —
A fewer suspended solids
B a lower temperature
C more dissolved salt (NaCl) particles
D* a higher concentration of OH– ions
Spring 2004 – 11:
(24) Bathwater normally has electrolytic behaviors even though distilled water does not.
This is because bathwater —
F contains isotopes of hydrogen
G has been heated
H is separated into H+ and OH– ions
J* contains dissolved minerals

37 The table shows data from an investigation designed to find a liquid solution that is
both an acid and a strong electrolyte. Based on the data, a solution that is both an acid and
a strong electrolyte is —
A Solution 1
B Solution 2
C Solution 3
D* Solution 4
Fall 2005 – 11:
22 Dissolving salt in water increases the conductivity of the solution because the —
F salt gives the solution a net negative charge
G salt ions bond with the available water molecules
H solution has an increase in kinetic energy
J* concentration of ions in the solution increases
