Answer to Question #122744 in General Chemistry for Mohamed

Question

52.0g of potassium chloride is added to a 100ml saturated solution of sodium nitrate at 80 deg C. A fine white precipitate is observed. [A] what is the precipitate? Justify your answer! [B] how much precipitate should you be able to filter out of the solution at most

Answer 1

a}. what is the precipitate? Justify your answer!

No precipitate is formed. this is due to fact that KNO₃ and Nacl are both water soluble products.

b} how much precipitate should you be able to filter out of the solution at most.

when solutions of potassium chloride and sodium nitrate are mixed the equation for the hypothetical double replacement reaction

52.0g of KCl

100ml of NaNO₃ at 80 degrees celcius

KCl_(aq) + NaNO_3(aq) - KNO_3(s) + NaCl_(s)

Even though we can write an equation for a double replacement no reaction occurs we simply end up with a solution containing four kinds of ions Na⁺ , K⁺ Cl^- and NO₃^-
