Chem Lab

Purpose:
To determine what factors assume the account of solution

Hypothesis:
If a concentration of CuSO4 x 5H2O is tampered with, then it impart affect the rate of dissociation. This includes adding heat to it and stirring it until it is dissolved.
* Concentration stirred in distilled pissing will affect it
* Heating & commovering Will affect the rate of solution
* Concentrated by amount of substance will affect it

Materials:
- Heating Plate- CuSO4 x 5H2O- Cover Glass
- parent Rod- White Paper- Stir Bar
- Four (4) one hundred fifty mL beakers- Scale
- Distilled Water- Stop Watch

Safety/Disposal:
uphold away from skin, do not inhale directly, ALWAYS weary goggles & an apron, toxic if ingested, nonflammable, use and dispense substance in a hood. Avoid contact with finely powdered metals and heat. cast away down the drain and RINSE thoroughly.

Procedure:
1. Obtain on the whole materials listed above

ruin 1 STIRRING

1. stern 10g of CuSO4 x 5H2O into a beaker with 20mL of distilled water.
2. Stir solution for a minute and record your observations
3. Repeat step 2 & 3 a total of 2 time so you have done it a total of 3 times
4. Record observations on rate of dissociation.

PART 2 HEATING

1. Place 10g of CuSO4 x 5H2O into a beaker with 20mL of distilled water.
2.



With a preheated heat dental plate on a setting of level 5, place the beaker on the plate and let sit for about 1 minute.
3. Record your observations.

PART 3 CONCENTRAION

1. Place 10g of CuSO4 x 5H2O into a beaker with 20mL of distilled water.
2. Place 15g of CuSO4 x 5H2O into a beaker with 20mL of distilled water.
3. Place 20g of CuSO4 x 5H2O into a beaker with 20mL of distilled water.
4. Stir exclusively solutions and record the time it takes each one to dissolve.
5. Record both last observations and then clean up your lab area.
