The ideal gas law (for one mole of gas) may be used to express pressure as a function of volume and temperature, ie p=p(V,T). Use this and the expression for the above total differential of G to obtain expressions for the partial derivatives natural to the function G=G(V,T)
Write two balanced half reactions for the titration of iodine with sodium thiosulfate. Indicate what is being oxidized and what is being reduced.
Automobile airbags contain solid sodium azide, NaN3, that reacts to produce nitrogen gas when heated, thus inflating the bag. Calculate the value of w (work) for the following system if 11.8 g of NaN3 reacts completely at 1.00 atm and 22 °C.
Describe how you will prepare a H2PO4-/HPO42- buffer using solid sodium dihydrogen phosphate and sodium hydrogen phosphate (pH 7.4, 500 mL 0.40M each).
