AgCl (s) + --> <-- Ag + (aq) + Cl- (aq) Shown above is information about the dissolution of AgCl in water at 298 K. In a chemistry lab a student wants to determine the value of s, the molar solubility of AgCl, by measuring [Ag+] in a saturated solution prepared by mixing excess AgCl and distilled water. How would the results of the experiment be altered if the student mixed excess AgCl with tap water (in which [Cl-] =...

You must ensure that the elements/ions making up the products are combine in the correct proportions. Additionally, you must include the physical state of each compound {ie (aq) or (g) or (s) or (I)}. If no...
