A salt has the form M2X3 where M is a metal cation and X is a nonmetal anion. If ΔGrxn is 80.40 kJ/mol, what is the concentration of the metal ion in a 100.0 mL aqueous solution? Assume the temperature is 25.0oC.
Consider a hypothetical salt of low solubility, "MX", where M+ is a metal cation and X- is a non-metal anion. A voltaic cell was set up with a cathode containing metal "M" immersed in a solution containing M+ at a concentration of 1.00 mol L-1. The anode consisted of metal "M" immersed in a saturated solution of "MX". The measured cell voltage was 0.251 V. What is the Ksp of "MX" at 25°C ?
What is the molar solubility (in mol L-1) of a salt in pure water with general molecular formula MX (where M is a cation and X is an anion) that has Ksp = 2.22 x 10-5 ?

Suppose we have a salt of low solubility, "MX", X- represents a non-metal anion M+ represents a metal cation. We then employ a voltaic cell with a cathode containing metal "M" immersed in a solution containing M+ at a concentration of 1.00 mol L-1. The anode consisted of metal "M" immersed in a saturated solution of "MX". The measured cell voltage was 0.355 V. Calculate Ksp of "MX" at 25°C

1) Rank the salts in order of increasing molar solubility.
2) Rank the salts in order of increasing Ksp
(remember 10–10 < 10–5)
3) If these rankings are not in the same order, why might
Ksp not always scale directly with molar solubility?
Design experiments in the virtual lab to answer the follow questions, 1). Use the virtual lab to determine the...
