A solution of malonic acid H2C3H2O4 was standardized by titration with .1000M NaOH solution. If 20.76mL of the NaOH solution were necessary to neutralize completely 13.15mL of the malonic acid solution, define what is the molarity of the malonic acid solution?
H2C3H2O4 + 2 NaOH ---> Na2C3H2O4 + 2 H2O
Write the total and net ionic equations for the reaction of BaSO4 dissociation, and calculate the trial Ksp for the product formed, when 40 mL of 0.1 M Ba(CH3COO)2 reacts with 60 mL 0.6 M MgSO4 and decide whether a ppt will form
