You have two beakers. One beaker contains 100 mL of NaOH (a strong
base); the other contains 100 mL of aqueous Na PO, (a weak base). You
test the pH of each solution. Which of the following statements is true? *
A)
It is possible for the solutions in each beaker to have the same pH.
B)
The Na PO, has a higher pH because it has more sodium ions than NaOH.
C) If the pH of the NaOH solution is 12.00, the pH of the Na PO, solutions has to be
greater than 12.00.
D) If the pH of the NaOH solution is 12.00, the pH of the Na PO, solution has to be less
than 12.00

One way in which the useful metal copper is produced is by dissolving the mineral azurite, which contains copper(ii) carbonate, in concentrated sulfuric acid. the sulfuric acid reacts with the copper(ii) carbonate to produce a blue solution of copper(ii) sulfate. scrap iron is then added to this solution, and pure copper metal precipitates out because of the following chemical reaction: (s) (aq) (s) (aq) suppose an industrial quality-control chemist analyzes a sample from a copper processing plant in the following way. he adds powdered iron to a copper(ii) sulfate sample from the plant until no more copper will precipitate. he then washes, dries, and weighs the precipitate, and finds that it has a mass of .
