At a pH of 4, the Cu-neocuproine complex formed in the liquid-liquid extraction experiment has a partition coefficient of about 6.5 when equilibrated between the acid aqueous solution and chloroform. Calculate the concentration of Cu in the chloroform phase if 39 mL of a 0.28 M aqueous Cu solution buffered to pH 4 is equilibrated with 12 mL of chloroform.
A sample of 87 mg of an ideal gas a 0.600 bar pressure has its volume doubled and its absolute temperature tripled. Find the final pressure.
The density of the hydrogen peroxide solution is 1.01 g/mL and the solution contains 3.40% H202 by mass. The vapor pressure of water at 24C is 22 mmHg. Based on this data and information calculate the molar volume at STP.
some gas is expelled from the bottle from the process. When P = P(external), the stopper is quickly replaced. The gas remaining in the bottle slowly warms up to 285K. what is the final pressure in the bottle for a monatomic gas for which C(v,m) = ..
At a given temperature, 1.18 atm of F2 and 5.91 atm of Br2 are mixed and allowed to come to equilibrium. The equilibrium pressure of BrF is found to be 1.044 atm. Calculate Kp for the reaction at this temperature. F2(g) + Br2(g) 2 BrF(g)
