Students can figure out what an unknown crystal is by comparing their dissolving test with the known and unknown crystals. This inquiry activity includes background information and student handout.

Demonstrate the effect that dissolving different amounts of salt in water has on the density of the liquid.

Students use conductivity meters to measure various salt and water solutions, as indicated by the number of LEDs (light emitting diodes) that illuminate on the meter. Students create calibration curves using known amounts of table salt...

Add different salts to water, then watch them dissolve and achieve a dynamic equilibrium with solid precipitate. Compare the number of ions in solution for highly soluble NaCl to other slightly soluble salts. Relate the charges on ions...

Read and learn about strong and weak Arrhenius bases. View the written formula and discover what certain solutions may be dissolved and which molecules can be transferred.

Lab activity where students determine the relationship of pressure and temperature on gas solubility.

This chemistry tutorial explains the gas laws (e.g., Boyle's Law) with applications.

At this site learn about Henry's law through this hands-on experiment. Lab instructions are complete including step-by-step pictures an worksheet.
