WebCorrect answer - If a dilute agno3 solution is slowly added to the solution, what is the first compound to precipitate: ag2cro4 ( ksp = 1.2×10−12), ag2c WebKsp = [Ag +][Cl −] = (x)(x) = 1.8 × 10 − 10 Solving for x gives [Cl −] as 1.3 × 10 –5 M, or a pCl of 4.89. Note Step 4: Calculate pCl after the equivalence point by first calculating the …
