What is the pH of a solution containing 0.10 mol/dm3 Citric Acid and 0.30 mol/dm3 Sodium Citrate? Citric Acid: Ka = 7.4 x 10^-4 mol/dm3
A 0.010 mol/dm3 aqueous solution of an acid HA has a pH of 2.0. Is HA a strong or a weak acid? Explain your answer.
If you have a solution that is 0.10 mol/dm3 in both Ba2+ and Ca2+. CaF2 will begin to precipitate first as fluoride ion is added slowly to the solution. i) What concentration of fluoride ion will precipitate the maximum amount
At 298K, the value of Ka of Ethanoic Acid in aqueous solution is 1.74 x 10^-5 mol/dm3 i) Calculate the pH of 0.410 mol/dm3 Ethanoic Acid in this temperature. ii) Calculate the pH of the buffer solution formed when 10
