Effect of Temperature on Solubility of a Salt

Experiment #12 from Chemistry with Vernier

In this experiment, you will

  • Study the effect of changing temperature on the amount of solute that will dissolve in a given amount of water.
  • Plot a solubility curve.

Recommended

Conductimetric Titration and Gravimetric Determination of a Precipitate

Experiment #16 from Advanced Chemistry with Vernier

In this experiment, you will

  • Measure the conductivity of the reaction between sulfuric acid and barium hydroxide.
  • Use conductivity values as a means of determining the equivalence point of the reaction.
  • Measure the mass of a product of the reaction as a means of determining the equivalence point of the reaction gravimetrically.
  • Calculate the molar concentration of a barium hydroxide solution.

Conductivity of Aqueous Solutions

Experiment #4 from Investigating Chemistry through Inquiry

In the Preliminary Activity, you will gain experience using a Conductivity Probe and data- collection software. You will first measure the conductivity of distilled water, and then, after adding NaCl solid to the distilled water, you will measure the conductivity of the resulting NaCl solution.

After completing the Preliminary Activity, you will first use reference sources to find out more about electrolytes and the electrical properties of aqueous solutions before you choose and investigate a researchable question dealing with the conductivity of aqueous solutions.
