MY and NY3N{Y}_{3} , two nearly insoluble salts, have the same Ksp{K}_{sp} values of 6.2×10−136.2 \times {10}^{- 13} at room temperature. Which statement would be true in regard to MY and NY3N{Y}_{3} ?MY and N Y _ 3 , two nearly insoluble salts, have the same K _ sp values of 6.2 × 10 ^ - 13 at room temperature. WhichMY and N Y _ 3 , two nearly insoluble salts, have the same K _ sp values of 6.2 × 10 ^ - 13 at room temperature. Which

Options

  1. AThe molar solubilities of MY and NY3N{Y}_{3} in water are identical.
  2. BThe molar solubility of MY in water is less than that of NY3N{Y}_{3} .
  3. CThe salts MY and NY3N{Y}_{3} are more soluble in 0.5 M KY than in pure water.
  4. DThe addition of the salt of KY to solution of MY and NY3N{Y}_{3} will have no effect on their solubilities.

Correct answer

B. The molar solubility of MY in water is less than that of NY3N{Y}_{3} .

Step-by-step solution

MY and N Y _ 3 , two nearly insoluble salts, have the same K _ sp values of 6.2 × 10 ^ - 13 at room temperature. Which

MY insoluble salt Ksp=s2{K}_{sp} = {s}^{2}

MY and N Y _ 3 , two nearly insoluble salts, have the same K _ sp values of 6.2 × 10 ^ - 13 at room temperature. Which

NY3N{Y}_{3} salt Ksp=s(3s)3{K}_{sp} = s{( 3s )}^{3}

=27s4= 27{s}^{4}

S=(ksp27)1nS = {( \dfrac{{k}_{sp}}{27} )}^{\dfrac{1}{n}}

SNY3{S}_{N{Y}_{3}} =(Ksp27)14= {( \dfrac{{K}_{sp}}{27} )}^{\dfrac{1}{4}} =(6.2×10−1327)14= {( \dfrac{6.2 \times {10}^{- 13}}{27} )}^{\dfrac{1}{4}}

∴S(MY)=6.2×10−13=7.8×10−7∴ {S}_{\left(MY\right)} = \sqrt{6.2 \times {10}^{- 13}} = 7.8 \times {10}^{- 7}

Solubility values

∴S(MY)<S(NY3)∴ {S}_{\left(MY\right)} < {S}_{\left(N{Y}_{3}\right)}
