- The solubility of an ionic compound MX (molar mass = 346 g) is 4.63 X 10-3 g/L. What is Ksp for the compound?arrow_forwardA student titrates 20.0 mL of 1.0 M NaOH with 2.0 M formic acid, HCOOH (K, = 1.8 x 104). Hypochlorous acid is an unstable compound and one of the decomposition products is chlorine gas, Cl2. The composition of the acid lowers its concentration over time. What effect will the decomposition of one-fourth of the acid have on the agreement between the endpoint of the titration and the equivalence point during a titration with standard sodium hydroxide? It is impossible to determine The endpoint would be before the ideal equivalence point The endpoint would be after the ideal equivalence point The endpoint will rema eerthe ideal egvaleacepolntarrow_forwardwhich of the following aqueous soluctions contains the lowest amount of ions or molecules dissolved in water? 1.5L of 0.75M HBr03 1.0L of 2.0M CaBr2 2.25L of 1.75M KBr 1.5L of 2.0M CH3OH 500. mL of 2.25M K3PO4arrow_forward
- The Ksp of aqueous magnesium hydroxide solution is 5.6 x 10-12 at 25 C. What is the molar concentration of magnesium ion in 1.00 L of this solution? What is the molar concentration of hydroxide ion in 1.00 L of this solution?arrow_forwardA fictional compound AX2 has a molar mass of 167.07 g/mol and a Ksp of 2.125e-11. It dissociates in water based on the equation: AX2(s) ↔ A²+ + (aq) + 2X (aq) Based on this information, label the statements below as true or false. True If more solid AX₂ is added to the system then [A²+] will increase. False If the solution is heated and the solubility decreases, then the heat of solution for AX₂ is endothermic. If soluble NaX is added to the system then [A²+] will increase. False True If more solid AX₂ is added to the system then [X] will decrease. True The molar solubility of AX₂ is less than 3.49E-4 mol/L. False If more soluble A(NO3)2 is added to the system then [X] will increase. True The mass solubility of AX₂ is greater than 1.46E-3 g/100mL H₂O. Submit Answer You have entered that answer before Incorrect.

- The generic metal hydroxide M(OH)2M(OH)2 has KspKspK_sp = 8.05×10−12. (NOTE: In this particular problem, because of the magnitude of the KspKsp and the stoichiometry of the compound, the contribution of OH−OH− from water can be ignored. However, this may not always be the case.) Part A) What is the solubility of M(OH)2M(OH)2 in pure water? Part B) What is the solubility of M(OH)2M(OH)2 in a 0.202 MM solution of M(NO3)2M(NO3)2?arrow_forwardIf 15.2 pg of water is dissociated from lithium carbonate pentahydrate, what amount of lithium carbonate pentahydrate was originally used?
