Week 25 Blog Reflection

This week started with a lab using the electrolysis apparatus (picture below). We added copper chloride to water and made electricity flow through it. We asked ourselves major questions like what is the formula for copper chloride? And which side of the apparatus is positive and which is negative? We also tested substances like sodium chloride and ethanol for comparison and measured conductivity for each one. Our results of this test are pictured below. We also discussed the concept of solubility, in our lab a chemical reaction changed the color when the powder went in the water. This showed us that when in water, it was no longer a compound. Like lady liberty! It turned green in the water. This week we also had a beach party! We mixed a caloric acid with ethanol and made a lovely campfire to roast our marshmallows for our s'mores!
