1. How do your observations reflect the solubility rules you learned from the textbook? Can you identify at least one mixture above for each solubility rule? My observations reflect the accuracy of the solubility rules. All common compounds of Group I and ammonium ions are soluble. All binary compounds of the halogens (other than F) with metals are soluble, except those of Ag, Hg(I), and Pb. All sulfates are soluble, except those of barium, strontium, calcium, lead, silver, and mercury (I) (latter 3

Unformatted text preview: are slightly soluble). Carbonates, hydroxides, oxides, silicates, and phosphates are insoluble unless combined with a group 1 element. Sulfides are insoluble except for calcium, barium, strontium, magnesium, sodium, potassium, and ammonium. The only solubility we did not get to test was “All nitrates, acetates, and chlorates are soluble” because we did not deal with nitrates, chlorates, or acetates. 3. Write a balanced net ionic equation for all reactions that appear to occur. For reactions that do not occur, write the two reactant ions and an arrow but do not list any products....

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
