a) Using the appropriate equations show why addition of 6M HCl to a saturated KCl solution does not produce a precipitate.
b) Why does the addition of 12M to the KCl solution produce a precipitate?
Homework Answers
KCl(aq)--------> K+ + Cl-
HCl ------------> H+ + Cl-
Due to common ion effect does not precipitate.By the addition of 6M HCl to KCl concentraction of Cl- ion increases . So concentration of products are increases reaction favored left side.

For each experiment described below 1) provide the relevant equilibrium reaction or reactions, 2) use LeChatelier's Principle to explain why the reaction has shifted left (L) or right (R), and 3) answer any other questions. a) To a solution containing 1M Pb(NO3)2, 1 M HCl is slowly added until a white precipitate forms. The mixture is then heated and the precipitate disappears. Is the dissociation of the precipitate endothermic or exothermic? Does the equilibrium constant (Ksp) change when the solution...

A student prepared a base solution using 7 mL of 6M NaOH diluted with distilled water to a final volume of approximately 400 mL. The student titrated a standardized solution of HCl to determine the exact concentration of the prepared base solution. In the first titration, she found that it took 22.47 mL of the base solution to neutralize 20.00 mL of a 0.98861 M HCl solution. In the second titration, she found that it took 20.12 mL of the...
