Answer to Question #56947 in General Chemistry for jgore
The combination is the pH of solution A, described below, followed by the pH of solution C, also described below. (Example: If the pH of solution A were 3.47 and the pH of solution C were 8.15, the combination would be 3-47-8-15.)
Determine the combination of the safe from the information below:
Solution A: is a 0.150 M solution of a weak monoprotic acid HX.
Solution B: is a 0.0500 M solution of NaX, the sodium salt of this acid. It has a pH of 10.55.
Solution C: is made by adding 12.0 mL of 0.2500 M KOH to 50.0 mL of Solution A.
