Q

What is boiling point elevation and why does it occur?

A

Boiling point elevation is when the boiling point of a solution is higher than the pure solvent. It occurs because the solvent particles require more enegy to escape

Q

What is freezing point depression and why does it occur?

A

Freezing point depression is when the freezing point of a solution is lower than the freezing point of the solvent. This occurs because the freezing point must be lower to slow the particles down and get the solvent out of the way

Q

What is the goal of a titration?

A

To find the concentration of an unknown solution using a known solution?

17
Q

How is a titration performed?

A
  1. Put unknown solution in flask with indicator
  2. Put known solution in burret
  3. add known solution until indicator changes color-equivalence pt.
  4. Use volune and concentration of known solution with volume of unknown to find concentration
