Measure 500ml of tap water in the 500cm3 beaker, then measure 5g of sodium hydrogen carbonate using the 50cm3 beaker and weight scale and place in the beaker of water, using the glass rod to dissolve it into the mixture.
Procedure- The procedure for this lab includes many simple steps and a few different things we are testing. Our first Procedure was to combine water and salt to see what kind of reaction it would make. First we fill the graduated cylinder with 100 ml of water. We then measured 1.0 grams of table salt on a balance to get an accurate amount. After, we took the measured amount of salt and poured it into the water filled beaker. Lastly, we watched and recorded the reaction.
Then, fill 3 measuring cylinders with 100ml of water. Measure out 15g of salt, using a balance, into 3 containers. That means that there are 5g of salt per pour boat. Add one pour boat of salt to one beakerful of water. Stir the solution (2) and then heat it up using a Bunsen burner. Add a temperature probe and wait for the water to start boiling. You will know when the solution is boiling, as it will bubble and produce water vapour. Repeat this 2 more times and then 3 times for 10, 15, 20 and 25 grams. Using this method you will be able to collect accurate, precise and reliable results. This method provides us with precise and accurate results as we are using equipment with a smaller
9) Trial E: Remove the syringe and empty the beaker. Add a Thermometer to the beaker. Add 200 mL of Room Temperature water to the beaker and heat with a Bunsen Burner until it reaches 100° C. Remove the Bunsen Burner. Repeat Steps 5 & 6.
4.Measure 35mL of warm water and add them into each of the 4 test tubes at about roughly the same time. It is essential that the water is warm. Do not seal the test tube.
First I will set up the apparatus as show above. I will add 1.5 grams
1. Measure out approximately 200 mL of distilled water and pour it into the calorimeter. Stir carefully with a thermometer until a constant temperature is reached. Record the volume of water and the constant initial temperature of the water on your data table.
2.) Assemble an apparatus for steam distillation using a large (250-500ml) boiling flask and a steam trap, and have your instructor check your apparatus. Apparatus was successfully assembled.
