Common Solution Equilibrium Calculation Questions with Working
This video will demonstrated worked examples for a variety of common solution equilibrium questions.
Watch the video for step by step explanations for the following questions.
Calculate the concentrations of barium and hydroxide ions in a saturated solution of barium hydroxide at 25ºC.
Calculate the maximum mass of NaOH(s) that can be added to 250.0 mL of 0.100 mol L–1 Ba(NO3)2(aq) solution before a precipitate is formed.
Determine whether a precipitate will form when 250.0 mL of 0.150 mol L–1 NaOH(aq) is mixed with 250.0 mL of 0.0800 mol L–1 Ba(NO3)2(aq) at 25ºC. Show relevant calculations.
Some amount of solid barium sulfate is added to 200.0 mL of 1.00 mol L–1 sodium sulfate at 25ºC. Calculate the solubility of barium sulfate in this solution.
