Distilled Water Procedure

Procedure: Research the topic. Collect all materials needed to conduct the experiment. The first experiment to be performed is the control test. During this time, it is optional to set up the video camera in front of the setup so that the entire experiment can be recorded. Make sure all the water, solutes, and equipment is at a steady room temperature. This is to ensure that temperature changes do not drastically alter the outcome of the experiment. Pour exactly 2 ounces of distilled water into the measuring cup. Transfer the distilled water into the boiling flask, making sure not to spill any of the water. Add the boiling stones into the flask carefully. Insert the rubber stopper on top of the boiling flask. Place the red spirit thermometer …show more content…

Do not scrub with a cloth or paper towel, and do not cool it by running it through cold water. Once all equipment has dried and cooled back to room temperature, measure out 2 ounces of distilled water in the measuring cup. Transfer the distilled water into the boiling flask. Then add the pieces of boiling stones into the flask. Using the weigh scale, prepare to weigh the solute. Do this by placing the small empty container on scale and then pressing the “tare” button on the scale. This brings the weight back to 0 grams, so that only the weight of the contents of the container are accounted for and not the actual weight of the container itself. Using the spoon, add salt to the container until 5 grams is recorded on the scale. Remove the container from the scale and carefully pour the salt from the container into the boiling flask. Slowly stir the solution using the glass stirrer until the salt has visibly …show more content…

Then remove the flask using the heat resistant gloves. Carefully remove the thermometer and pull out the rubber stopper. Pour the solution out through a strainer into the sink. Remove the boiling stones from the strainer and put them aside. Let all equipment sit for 10 minutes. Repeat steps 15-29 using 10 grams of salt, 15 grams of salt, and 20 grams of salt. Make sure to record the boiling points for each concentration of salt in the lab notebook. For example, when the temperature steadies out during the test using 10 grams of salt, note down the temperature as the boiling point reached using 10 grams of salt. Do the same for the 15 grams of salt and 20 grams of salt. At the end of the salt test, there should be 4 data points collected as shown in step 24. Once using salt as the solute is complete, repeat steps 15-30 using sugar in place of salt, then baking soda in place of salt. Make sure to collect the data properly and in the same format and separate from each solute. The same format of recording the data from Step 24 is used for each solute. Analyze the recorded
