Purpose: To determine what factors assume the account of solution conjecture: If a concentration of CuSO4 x 5H2O is tampered with, and then it impart appropriate the rate of dissociation. This includes adding heat to it and stirring it until it is dissolved. * Concentration stirred in distilled pissing will print it * Heating & commovering Will affect the rate of solution * Concentrated by amount of affection will affect it Materials: - Heating Plate- CuSO4 x 5H2O- Cover furnish - parent Rod- White Paper- Stir Bar - Four (4) sensation hundred fifty mL beakers- Scale - Distilled Water- Stop grab Safety/Disposal: uphold away from skin, do not inhale directly, ALWAYS weary goggles & an apron, toxic if ingested, nonflammable, use up and dispense substance in a hood. Avoid intimacy with finely powdered metals and heat. cast away down the enfeeble and RINSE thoroughly. Procedure: 1. Obtain on the whole materials listed supra 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. restate step 2 & 3 a entireness of 2 succession so you have done it a total of 3 times 4. Record observations on rate of dissociation. element 2 HEATING 1. manoeuvre 10g of CuSO4 x 5H2O into a beaker with 20mL of distilled water. 2. With a preheated heat dental plate on a ground of level 5, place the beaker on the plate and let sit around for about 1 minute. 3. Record your observations. PART 3 CONCENTRAION 1. array 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 cle an up your lab area. information: TR!
