Given the Ksp values for the following precipitates, please predict which precipitate has the largest solubility in the presence of 0.01 M of its composing anions (e.g., in the presence of 0.01 M Cl- ion for AgCl(s)):
Ksp, AgBr(s) = 5.0*10-13Ksp, AgCl(s) = 1.8*10-10Ksp, Ag2CO3(s) = 8.1*10-12Ksp, Ag2CrO4(s) = 1.2*10-12
Calculate the pH of a 3.92×10^-3 M solution of H2SO4. (Ka = 0.0120 for HSO4-) 3-In a 4.66×10^-2 M solution, a monoprotic acid, is 20.4% dissociated. Calculate Ka for this acid
When optically active B was treated with CrO3 in pyridine, an optically inactive sample of A was obtained. Heating A with hydrazine in base gave hydrocarbon C, which, when heated with alkaline KMnO4, gave carboxylic acid D. Identify compounds A, B..
