Activity and Concentration
funnel.sfsu.eduBut ions don’t behave ideally . . . •Concentration related to activity using the activity coefficient γ, where [a] = γ (c) •The value of γ depends on: –Concentration of ions and charge in the solution –Charge of the ion –Diameter of the ion •Ionic strength, I = concentration of ions and charge in solution I = 1/2 Σm i z i 2 ...
Precipitation Titration: Determination of Chloride by the ...
academic.brooklyn.cuny.eduThe Mohr method uses chromate ions as an indicator in the titration of chloride ions with a silver nitrate standard solution. After all the chloride has been precipitated as white silver chloride, the first excess of titrant results in the formation of a silver chromate precipitate, …
STOICHIOMETRY: The Reaction of Iron with Copper (II) …
www.ccri.eduIron forms 2 types of ions, namely Fe+2 and Fe+3. We shall use stoichiometric principles to determine which of these ions is formed in the reaction between iron and copper (II) sulfate solution. If Fe+2 is formed, then equation (1) is correct, while equation (2) is …
EXPERIMENT 1: HARDNESS OF WATER BY EDTA TITRATION …
www.calstatela.eduFill your burette with the EDTA solution. Pipet three 25 mL aliquots of standard calcium solution into 250 mL Erlenmeyer flasks, add 3 mL ammonium chloride buffer (pH 10) (operate in hood!) and 2-3 drops of Eriochrome Black T indicator solution. Titrate with EDTA from violet through wine-red to blue. It is recommended to experiment with a 5
Answer - Open Yale Courses
oyc.yale.eduSolution Quick overview: Although relativity can be a little bewildering, this problem set uses just a few ideas over and over again, namely 1. Coordinates (x;t) in one frame are related to coordinates (x0;t0) in another frame by the Lorentz transformation formulas. 2. Similarly, space and time intervals (¢x;¢t) in one frame are related to inter-
