Question

When we mix together, from separate sources, the ions of a slightly soluble ionic salt, the salt will precipitate if Q${}_{sp}$ ............... K${}_{sp}$, and will continue to precipitate until Q${}_{sp}$ .............. K${}_{sp}$.

• A. is greater than; equals
• B. is less than; is greater than
• C. is less than; equals
• D. equals; is less than
• E. equals; is greater than

Answer 1

The correct option is A is greater than; equals

When the ionic product is greater than solubility product, precipitation will occur. The precipitation will continue to occur till a point when the ionic product becomes equal to the solubility product.
