5/2/21 Which is Ionic?

Purpose: To find out which substance is ionic. Hypothesis: Substance#1 is ionic while substance#2 isn’t. Materials: aluminum foil, mini beakers, 2 beaks of unknown substances, sharpie marker, scooper, thongs, safety goggles, and a heat plate. Procedure: Step 1. Use mini beakers to shape the foil into cups. Step 2. Write #1 and #2 on each cup with a sharpie. Step 3. Use scooper to get 2 scoops of unknown substance #1, and put into cup #1. Do the same with cup #2. Step 4. Turn on the heat plate, and put on safety goggles. Step 5. Put foil cup #1 on the heat plate for five minutes. Check if substance has melted, then use the thongs to put cup on the table. Repeat this for cup #2. Step 6. Turn off/unplug the heat plate. Step 7.Write observations for before, and after. Do analysis, and conclusion. Observations: Before: Substance #1 and #2 are in a white grainy solid form. After:#1-melted within five minutes, and turned into a brown liquid. #2-didn’t melt within five minutes, and is still in a grainy solid. Analysis: Substance #1 is ionic melted while on the heat plate after five minutes. Substance #2 didn’t melt after five minutes. #1 and #2 were similar in form before, but not after. This proves that #1 and #2 are different substances. Therefore, #1 seems to be ionic while #2 isn’t. Conclusion: Substance #1 is ionic because it melted on the heat plate after five minutes while #2 didn’t. #1 seems to be salt, and #2 seems to be sugar. They are both very similar to each other normally. However, they’re very different. Possible errors may include: off timing, and the heat plate being broken. In conclusion, substance #1 is ionic....
