1.7C: Practical: Investigate the Solubility of a Solid in Water at a Specific Temperature



SOLUBILITY: How much of a substance will dissolve in a given volume of a solvent (shown in the units of g per 100g of solvent)

INVESTIGATING SOLUBILITY OF SOLIDS AT SPECIFIC TEMPERATURES

Diagram showing a Solid in Set Temperature of Water to Measure Solubility
METHOD:

  • Set water bath to specific temperature
  • Use water from water bath and add into Beaker
  • Add solid into the beaker and measure time taken for Solid to dissolve

RESULT:

  • As temperature of Water increases, time taken for Solid to dissolve will decrease (more soluble)
  • This occurs as increase in temperature increases the kinetic energy of particles, overcoming the intermolecular forces of attraction between solid particles
  • This causes particles to break apart, increasing solubility of Solid as a result

    Is anything like this available for other subjects as well?

    You're seriously confusing me, the time for water to dissolve should decrease as it gets more soluble, you said it increases. I've spent the last half an hour looking up if that is true and you are wrong. Ugh fix it please

    the water doesn’t dissolve, it’s the solid that dissolves and it should dissolve quicker when it is warmer

    The water doesn't dissolve you idiot it is the solvent not the solute.
    The author of this page has put time and effort it to this to help other people so shut the hell up!
