Determine if a precipitate will form when equal volumes of 1.64 x 10-3 M HCl and 8.48 x10-7 M AgNO3 are mixed to produce AgCl. Ksp AgCl = 1.6 x10-10. Determine the value of Q and report it as a -log value. If -logQ <9.796 a precipitate will form.
During the separation process students frequently examine that their sodium hydroxide solution is colored because of hydrolysis of small quantities of acetaminophen by sodium hydroxide to form 4-aminophenol
