Question

To test the hypothesis above, you changed the

of the solvent and
measured the
of a solid.

Answer 1

The student's question deals with a chemistry experiment focused on the effects of temperature on solubility. Steps involve preparing a solution, measuring boiling points or solubility, and applying laws like Henry's law to understand the solubility of gases at different pressures.

Step-by-step explanation:

The question revolves around changing the temperature of a solvent and measuring the solubility of a solid, which is a typical procedure in a chemistry experiment. To test the hypothesis that changing the temperature affects solubility, one would follow certain steps. For example, after preparing a solution as shown in figure 5.5.1, you would adjust the temperature and measure the new boiling point or solubility, as discussed in Step 4. Step 3 emphasizes the importance of thinking about the result and mentions that solubility increased to 4.5 times its original value due to a direct relationship. The 'Check Your Learning' section references using Henry's law to calculate the solubility of a gaseous solute at varying pressures. The final answer illustrates a change of state from gas to solid to liquid due to pressure changes, another principle in physical chemistry.
