Solution: KNO3, KClO3, KCl, and NaCl are recrystallized as follows:Step 1. A saturated aqueous solution of the compound is prepared at 50°C.Step 2. The mixture is filtered to remove undissolved compound.Step 3.

Problem

KNO3, KClO3, KCl, and NaCl are recrystallized as follows:

Step 1. A saturated aqueous solution of the compound is prepared at 50°C.
Step 2. The mixture is filtered to remove undissolved compound.
Step 3. The filtrate is cooled to 0°C.
Step 4. The crystals that form are filtered, dried, and weighed.

(b) Starting with 100. g of each compound, how many grams of each can be recovered?
