Ag2CrO4→ 2Ag2+ + \( CrO_{4}^{-}\)
Now, Ksp = [Ag2+]2\( [CrO_{4}^{-}]\)
Assuming the solubility of Ag2CrO4 is ‘x’.
Thus,[Ag2+] = 2x and \( CrO_{4}^{-}\) = x
Ksp = \( (2x)^2×x\)
\( 1.1\times 10^{-12} = 4x^{3}\)
\( x = 0.65\times 10^{-4}M\)
Assuming the solubility of AgBr is y.
AgBr(s) → Ag2+ + Br–
Ksp = (y)2
\( 5.0\times 10^{-13} = y^{2}\)
y = \( 7.07\times 10^{-7}M\)
The ratio of molarities to their saturated solution is:
\( \dfrac{x}{y} = \dfrac{0.65\times10^{-4}M}{7.07\times10^{-7}M} = 91.9\)
Answered by Abhisek | 1 year agoThe concentration of sulphide ion in 0.1M HCl solution saturated with hydrogen sulphide is 1.0 × 10–19 M. If 10 mL of this is added to 5 mL of 0.04M solution of the following: FeSO4, MnCl2, ZnCl2 and CdCl2 . in which of these solutions precipitation will take place?
What is the minimum volume of water required to dissolve 1g of calcium sulphate at 298 K? (For calcium sulphate, Ksp is 9.1 × 10–6).
What is the maximum concentration of equimolar solutions of ferrous sulphate and sodium sulphide so that when mixed in equal volumes, there is no precipitation of iron sulphide? (For iron sulphide, Ksp = 6.3 × 10–18).
The ionization constant of benzoic acid is 6.46 × 10–5 and Ksp for silver benzoate is 2.5 × 10–13. How many times is silver benzoate more soluble in a buffer of pH 3.19 compared to its solubility in pure water?
Equal volumes of 0.002 M solutions of sodium iodate and cupric chlorate are mixed together. Will it lead to precipitation of copper iodate? (For cupric iodate Ksp = 7.4 × 10–8 ).
