Raising the pH by the addition of sodium hydroxide can successfully precipitate the heavy metal copper from industrial waste. The insoluble precipitates can be easily removed accordingly. A solution is 0.0250 M in copper nitrate. Calculate the mass of sodium hydroxide that must be added to 1.00 L of this solution to remove copper. Assume that the following reaction proceeds to completion.
Cu(NO3)2 (aq) + 2 NaOH (aq) → Cu(OH)2 (s) + 2 NaNO3 (aq)
