Enter your parent or guardian's email address: Already have an account? Place the unknown cups aside. Explain that each powder will react in a certain way with each solution used to test it. Try Numerade free for 7 days. Discuss the difference in properties. Each chemical compounds has a certain percentage of ionic character in its bonds and the remaining percentage as covalent bonds. 3. react in 250 mL beaker. I picked these three because they allow you to measure with certainty to the tenths place, and you can estimate at the hundredths place. Put the substance in a 25 mL beaker Observe and record in the data table its | Course Hero. Ask students: - Both powders looked similar at first. These ions attract each other and create an ionic bond. 00 mL you want something that estimates to the hundredths place, so you are going to want to use something like a buret or a pipet.
