Question:
When an ionic compound such as sodium chloride (NaCl) is placed in water the componentatoms of the NaCl crystal dissociate into individual sodium ions (Na+) and chloride ions (Cl-). Incontrast, the atoms of covalently bonded molecules (e.g., glucose, sucrose, glycerol) do notgenerally dissociate when placed in aqueous solution. Which of the following solutions would beexpected to contain the greatest number of particles (molecules or ions)?
A) 1 L of 0.5MNaCl
B) 1 L of 0.5Mglucose
C) 1 L of 1.0MNaCl
D) 1 L of 1.0Mglucose
E) C and D will contain equal numbers of particles.
Answer:
C) 1 L of 1.0MNaCl
