Since HCl is composed of H and one other element it is named by the rule for binary acids: Hydro chlor ic Acid Other examples: HBr- Hydrobromic Acid, HF- Hydrofluoric Acid (B) Oxy acids (acids containing oxygen) If polyatomic ion ends in –ate: _____ic acid If polyatomic ion ends in –ite: ____ous acid Name H 2 SO 4 Since the acid contains O, it is named by the rules for oxy acids. SO 4 is named sulfate (see polyatomic ion list for name). Since SO 4 ends in -ate the acid is named: Sulfur ic Acid Other examples: HNO 3 - Nitric Acid, H 3 PO4- Phosphoric Acid Name H 2 SO 3 Since the acid contains O, it is named by the rules for oxy acids. SO 3 is named sulfite. Since SO 3 ends in -ite the acid is named: Sulfurous Acid Other examples: HNO 2 - Nitric Acid, H 3 PO 3 - Phosphorus Acid

    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.
