Gregory Bosch Jr. September 19, 2006 Chemistry Notes: Dilution M1V1 = M2V2 You want to know how much of one solution you must take in order to make a certain amount of another substance. 51,29g Ba(CH)2 is dissolved as 1.20 l. how many ml must be diluted to make 1.00 l of 0.100 M Be(OH)2? V1 = M2(V2/M1) Which of the following solutions contains the greatest number of ions? a. 400.0 mL of 0.10 M NaCl b. 300.0 mL of 0.10 M CaCl2 c. 200.0 mL of 0.10 M FeCl3 d. 800.0 Ml of 0.10 M sucrose Acids/Bases Arrhenius Definitions: Acid – yields H+ in solution Base – yield OH- in solution Brensted-Lowry Definitions: Acid – proton donor Base – proton acceptor If a compound gives up a proton, then it is an acid, however it a compound or substance of some sort accepts this proton, then it is a base, instead.

Unformatted text preview: A molecule acts as an acid or a base only with respects to its reaction with water. TERMINOLOGY Strong Acid/Base dissociates completely in water. Weak Acid/Base dissociates only partially. TITRATION: measured reaction of acid with base I to a certain endpoint. 3 Terms: Neutralization point: acid/base react up to neutral solution. Equivalous Point: base added sufficient to react with all the acid. (not necessarily neutral) Strong: Acids Bases HCl NaOH HBr KOH HNo3 HCl)4 H2SO4 Most of the other acids or bases are weak. Strong and weak does not mean how powerful or vicious the compound may be, but in respect only to how it dissociates in water! IMPORTANT PH: Defined: pH = -log10(H+) pOH = -log10(OH-) pK = -log10K...

    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.
