Inquire: Factors that Affect Solubility  

Solubility Problems

Many people have encountered common solubility problems in everyday life. Maybe it was caused by knocking over a candle, spilling candle wax on the table. Or, it could have been from spilling cooking oil on the kitchen floor while preparing a meal. These spills are nearly impossible to remove with just water.
