Free Solubility Product MCQs with Answers
23 Solubility Product MCQs from Chemistry, each with the correct answer and a written explanation of why it is correct. Free and unlimited, with no account needed.
The solubility product constant, Ksp, represents the equilibrium concentrations of ions from a sparingly soluble salt, each raised to its stoichiometric power. Problems involve writing Ksp expressions, calculating molar solubility, applying the common-ion effect and predicting precipitation from the ionic product.

- A. the total mass of the salt dissolved
- B. the product of the concentrations of its ions in a saturated solution, each raised to the power of its coefficient
- C. the concentration of the undissolved solid
- D. the ratio of dissolved to undissolved salt
Explanation: For a saturated solution in contact with excess solid, an equilibrium exists between the solid and its ions, and Ksp is the equilibrium…
Correct answer: the product of the concentrations of its ions in a saturated solution, each raised to the power of its coefficient- A. Ksp = [Ag+] + [Cl-]
- B. Ksp = [AgCl] divided by [Ag+][Cl-]
- C. Ksp = [Ag+][Cl-] divided by [AgCl]
- D. Ksp = [Ag+][Cl-]
Explanation: Silver chloride dissociates into one silver ion and one chloride ion, so Ksp is simply the product of the two concentrations, and the…
Correct answer: Ksp = [Ag+][Cl-]- A. no more solid can be added to the container
- B. the dissolved ions are in equilibrium with the undissolved solid
- C. the salt has completely dissolved
- D. the solubility product has been exceeded
Explanation: In a saturated solution ions leave the solid surface and return to it at the same rate, so the concentration of dissolved ions stays…
Correct answer: the dissolved ions are in equilibrium with the undissolved solid- A. Yellow
- B. Light Yellow
- C. Brown
- D. Blue
Explanation: Silver iodide is a yellow precipitate because Ag+ reacts with I− to form the sparingly soluble compound AgI, which has a characteristic…
Correct answer: Yellow- A. Yellow
- B. Green
- C. Blue
- D. White
Explanation: Silver chloride forms a white curdy precipitate because Ag+ combines with Cl− to produce insoluble AgCl.
Correct answer: White- A. Alkali metals
- B. Aldehydes
- C. Halides
- D. Ketones
Explanation: Silver nitrate detects halide ions because Ag+ forms insoluble precipitates with Cl−, Br− and I−, allowing their presence and amount to be…
Correct answer: Halides- A. Hg, Pb
- B. Zn, Mn
- C. As, CD
- D. Cd , Pb
Explanation: Passing H2S precipitates both Hg2+ and Pb2+ as dark sulfides, so this pair is not readily distinguished by the colour of the initial H2S…
Correct answer: Hg, Pb- A. CuS
- B. CdS
- C. PbS
- D. AgCl
Explanation: AgCl is insoluble in nitric acid because its ionic lattice is not sufficiently broken by HNO3, whereas sulfides such as CdS and PbS…
Correct answer: AgCl- A. BaSO4
- B. SrSO4
- C. CaSO4
- D. MgSO4
Explanation: The solubility of alkaline-earth sulfates generally increases up the group, so MgSO4 is much more soluble in water than CaSO4, SrSO4 and…
Correct answer: MgSO4- A. saturated solution
- B. solubility
- C. unsaturated solution
- D. super saturated solution
Explanation: The concentration of solute present when a solution is in equilibrium with undissolved solid at a fixed temperature is its solubility.
Correct answer: solubility- A. KCIO4
- B. Na2SO4. 10H2O
- C. K2Cr2O7
- D. PbCl2
Explanation: Na2SO4·10H2O shows a discontinuity in its solubility curve because the decahydrate changes to another solid form at a transition…
Correct answer: Na2SO4. 10H2O- A. continuous and falling solubility curve
- B. discontinuous and falling solubility curve
- C. continuous and rising solubility curve
- D. discontinuous and rising solubility curve
Explanation: The solubility of KClO3 increases continuously as temperature rises because no solid-state transition interrupts the curve, and the…
Correct answer: continuous and rising solubility curve- A. Ka
- B. Kb
- C. Kc
- D. Ksp
Explanation: The solubility of a sparingly soluble ionic salt is determined from its solubility product, Ksp, using the ion concentrations in the…
Correct answer: Ksp- A. common ion effect
- B. solubility product
- C. dissociation constant
- D. dissociation constant for an acid
Explanation: For a sparingly soluble salt at equilibrium, the product of the molar concentrations of its ions, each raised to its stoichiometric power…
Correct answer: solubility product- A. NaCI
- B. Na2SO4
- C. Na2CO3
- D. FeCl3
Explanation: Na2CO3 gives CO3^2− ions, which react with water to produce OH− ions, making the solution basic.
Correct answer: Na2CO3- A. 2.0 x 10^-10 mol dm-3
- B. 1.414 x 10^-5 mol dm-3
- C. 1.0 x 10^-10 mol dm-3
- D. 1.0 x 10^-5 mol dm-3
Explanation: For AgCl(s) ⇌ Ag+ + Cl-, if the solubility is s mol dm-3, then [Ag+] = [Cl-] = s and Ksp = s2.
Correct answer: 1.414 x 10^-5 mol dm-3- A. dilute and concentrated
- B. dilute and saturated
- C. saturated and unsaturated
- D. saturated and super saturated
Explanation: A solution may be both dilute and saturated when the solute has low solubility: it contains only a small amount of solute, yet that amount…
Correct answer: dilute and concentrated- A. Li2CO3
- B. KI
- C. NaCl
- D. Both option A and B
Explanation: Li₂CO₃ (Lithium carbonate)Endothermic dissolution → solubility increases with temperature.KI (Potassium iodide)Dissolution is endothermic…
Correct answer: Both option A and B- A. Increases with temperature

Explanation: The solubility of most salts increases with temperature due to increased kinetic energy and greater interaction between solute and solvent…
Correct answer: Decreases with temperature- A. 4.0 x 10^-4 M
- B. 2.0 x 10^-2 M
- C. 8.0 x 10^-4 M
- D. 2.0 x 10^-4 M
