Question

Prepare NaOH and HCl Solutions: 1. Using the graduated cylinder, place 50.0 mL of distilled water into the Erlenmeyer flask. Be exact with the volume. 2. Using the weigh boat, weigh out as exactly as you can 2.00 g of the solid NaOH. Carefully add the NaOH to the distilled water in the flask and stir well. This should be a 1.0 M NaOH solution. 3. Record the molarity of the NaOH solution on the lab report. 4. Using the graduated cylinder, transfer 50.0 mL of NaOH solution to the calorimeter. 5. Measure out 34.0 mL of the distilled water and place it in the flask. 6. Measure out 17.0 mL of the 3 M HCl solution and pour it into the flask with the water. 7. Mix the solution well with the stirring rod. This will give you a 1.0 M solution of the HCl. 8. Record the molarity of the HCl on the lab report. 9. Measure 50.0 mL of HCl solution in the graduated cylinder and record the exact volume to the correct number of significant figures as this will affect the moles of acid calculation. Complete this table: Solutions Volume Volume of NaOH solution mL Molarity of NaOH solution M Volume of HCl solution mL Molarity of HCl solution M Assume that the density of the solution is 1.00 g/mL and its specific heat is 4.184 J/g oC. With Î”T=8.0oC, calculate q solution.
