Is it true that Ksp is an equilibrium constant that can be used to express quantitatively the extent to which a compound dissolves?
Calculate the volume of water added to 0.410 L of 0.0340 M sodium hydroxide to obtain a 0.0110 M solution (assume the volumes are additive at these low concentrations).
To find the % by mass of a compound in a given sample - Determine the percent by mass of calcium carbonate in the sample. State any assumptions.
Once ready, he put a bit of sand on top. He loaded about 1 gram of product that had been dissolved in 1 ml of ethyl acetate.
Determine the pH of the solution containing 8*10^(-3) M each of HF and NaF. Assume that NaF dissociates completely. Acid Dissociation constant for HF is Ka=6.3*10^(-4).
Why has fluorine been added? The structure is Cephalosporin.
What value do you get for E using the Nernst Equation? The equation is E standard = -RT/nFln[1/Cu]. The values to plug in are E = 0.340 - (8.314*298)/(2*96500)ln[1/0.10]. I calculated E = 0.31044 V. Is this correct. Any help appreciated
