Reaction 1 Reaction 2 Reaction 3 Step 1: Steps Step 1: Take out 50ml graduated cylinder & foam cup (Glassware Menu). Take out scale (Tools Menu). Move distilled water & solid NaOH (Chemical Stockroom) Take the 0.5M HCI from strong acids cabinet and a foam cup and 50ml graduated cylinder from the glassware menu and place them on the wvorkbench. Take out another graduated cylinder, a fresh foam cup, the 1.0 M HCI and the 1.OM NaOH. Measure 25.0 ml of 1.0 M hydrochloric acid solution into the foam cup. Pour an equal volume of 1.0M sodium hydroxide solution in the clean graduated cylinder. Step 2: Transfer water to foam cup, drag the carboy of water on graduated cylinder. A transfer text bar enter 50.0 ml and click on pour. Procedure to reaction 2 closely related to reaction except that 50.0 mi of 0.5OM hydrochloric acid solution used in place of water. Step 2: Step 3: After measuring 50.0ml of the HCI solution into the graduated ylinder, proceed as before with step 2 through 4 of the procedure. Record the temperature of each solution to the nearest 0.1'C. Pour the sodium Weight 1 gram solid sodium hydroxide pellets, NaOH(s) then record mass nearest 0.01 gram. Place foam cup on balance and click tare button. Drag NaOH onto foam cup. Next, type 1.00 gram then pour. hydroxide solution into the foam cup and record the highest temperature obtained during the reaction. Step 4: Click graduated cylinder, record temperature and drag to foam cup. Enter 50.0 in transfer bar and then click pour. Record the highest temperature.
