Looking for chemical compounds in the world around us… I SPY Looking for chemical compounds in the world around us…

Instructions The following slides contain images of household items with their ingredient labels On each slide I will tell you how many ionic and covalent molecules to look out for In your notebook, write down the name of each compound you find, state whether it’s ionic or covalent, then write it’s chemical formula Don’t include any compounds that don’t follow traditional naming rules! Good luck!

I spy: 1 covalent compound & 2 ionic compounds!

Near the end of the ingredients list you will find “Titanium dioxide” Near the end of the ingredients list you will find “Titanium dioxide”. Explain why this name is not traditional for this type of compound.

“Activate” water is “Deionized water + electrolytes”—explain why this is ironic.

Images like this frequently get circulated around the internet Images like this frequently get circulated around the internet. Look at all the things that had potassium chloride and evaluate the claim—is the potassium chloride in Dasani harmful? Why or why not?

Have you completed the I spy?

Are you sure?

Answer Key—arranged by slide number N/A Water—covalent—H2O magnesium sulfate—ionic—Mg(SO4) potassium chloride—ionic—KCl 4. Sodium hydroxide—ionic—Na(OH) magnesium chloride—ionic—MgCl2 5. Carbon dioxide—covalent—CO2

Answer Key—arranged by slide number Ammonium phosphate—ionic—(NH4)3(PO4) potassium phosphate—ionic—K3(PO4) potassium chloride—ionic—KCl Carbon monoxide—covalent—CO Sodium bicarbonate—ionic—NaHCO3 Silicon dioxide—covalent—SiO2 sodium hydroxide—ionic—NaOH sodium chloride—ionic—NaCl

Answer Key—arranged by slide number 11. Titanium dioxide contains a metal and a non-metal, so it is ionic— ionic compounds don’t usually have prefixes in their names. 12. “Deionized” means they remove all the ions, but “electrolytes” are ions—why would they take the ions out just to put them back in? 13. Like any chemical, potassium chloride can cause death if you have too much. But in small amounts, it is actually used as a medicine to treat low blood pressure. Remember, just like with dihydrogen monoxide, do your research when you see stuff like that!
