    Calculating pH & pOH of AgNO2 Solution

    woops [NO2-]i = .006499 y= .0300 = [OH-] pOH = 1.52 pH = 12.35

    Calculating pH & pOH of AgNO2 Solution

    Ok Here is what I am thinking, let me know if this seems right: .1gAgNO2/.1L*(1mol/153.875g)*(1mol Ag+/mol AgNO2) = .006499M Ag+ = x Similarly .006499M NO2- = x Q = x^2 = 4.2x10^-5 < Ksp => not saturated (all will disolve) now [NO2-]i = 4.2x10^-5 setting up ice table yields: Kb...

    Calculating pH & pOH of AgNO2 Solution

    My thinking on the approach was that although the Ksp is small (i.e. not much will go into solution) since NO2- + H2O ----> HNO2 + OH- has a Kb = .1389 (Kw/Ka) it will shift the initial equilibrium of AgNO2 <---> Ag+ + NO2- to the right. I still don't know where to go though and I really need...

    Calculating pH & pOH of AgNO2 Solution

    Homework Statement If 0.1g of Silver Nitrite (AgNO2; ksp = 6 x 10^-4) is added to 100 mL of water, what would the pH and pOH be? Note: The Ka for HNO2 is 7.2 x 10^-4 Homework Equations The Attempt at a Solution I really am not sure how to approach this except for the fact that...

    Ice added to Water (heats of rxn)

    Homework Statement If 24g of ice at -5C is added to a isolated dewar containing 50 mL of water at 10C. What would the temperature of the system be at equilibrium if the heat capacity can be ignored and the system is completely isolated. Homework Equations sp ht H2O (l) - 4.18 J/(gC)...
