the solubility product expression for BiS3 is Ksp=
a.[Bi2^3][S3^2-].
b. [Bi^3+][S^2-].
c. [Bi^3+]^2 [S^2-]^3
d. none of these
Do you know the definition of Ksp. That will tell you which is the correct answer. What is it you don't understand about the question? BTW, are you sure it isn't Bi2S3?
To determine the solubility product expression for BiS3, we need to identify the formula of BiS3 and then write the corresponding expression using the correct stoichiometric coefficients.
The formula for bismuth sulfide is Bi2S3. From the formula, we can determine that each molecule of Bi2S3 contains two bismuth ions (Bi^3+) and three sulfide ions (S^2-).
The solubility product expression represents the equilibrium constant for the dissociation of a sparingly soluble compound into its constituent ions in a solution. It can be expressed as the product of the concentrations of the ions, each raised to the power of their respective stoichiometric coefficients.
Therefore, the correct solubility product expression for BiS3 (Bi2S3) is:
a. [Bi^3+]^2 [S^2-]^3
Hence, the answer is (c) [Bi^3+]^2 [S^2-]^3.
