Asolution containing a mixture of 0.0379 m potassium chromate ( k2cro4 ) and 0.0739 m sodium oxalate ( na2c2o4 ) was titrated with a solution of barium chloride ( bacl2 ) for the purpose of separating cro2−4 and c2o2−4 by precipitation with the ba2+ cation. the solubility product constants ( ksp ) for bacro4 and bac2o4 are 2.10×10−10 and 1.30×10−6 , respectively. which barium salt will precipitate first?

BaCrO₄ will precipitate first.

Explanation:

For a generic salt (AB) that is soluble in some solvent, the solubility product constant (Kps) is:

AB(s) ⇄ A⁺ + B⁻

Kps = [A⁺]*[B⁻]

So, as greater is Kps, as higher is the solubility, and more difficult will be to form a precipitated (the solid form of the salt).

Kps of BaCrO₄ < Kps of BaC₂O₄, so BaCrO₄ will precipitate first.

lol idk man i guess u gotta ask bill nye the science guy

if you're asking what comes out, it's steam.
