Salts Containing Only Doubly or Triply Charged Ions Are Often

question 8

Multiple Choice

Salts containing only doubly or triply charged ions are often insoluble in water. This could be because

• A) the ions are highly charged, and a large number of water molecules is organized around them, so DS is negative.
• B) the ions are highly charged, hence the lattice energy is very large, and DH therefore tends to be negative.
• C) the ions are very large, hence the lattice energy is very large, and DH is positive.
• D) both a and b.
• E) both a and c.
