(a) A 30.00mL solution containing NaOH, Na2C03, and NaHC03, alone or in compatible combination was titrated with 0.1322M standard HCl. It took 30.45mL to reach the phenolphthalein end point and 41.13mL to reach the bromocresol green end point. Deduce the composition of the solution and calculate the concentration of eachsolute in mg/mL of solution.
(b) A 25.00mL solution containing NaOH, Na2C03, and NaHC03, alone or in compatible combination was titrated with 0.1221M standard HCl. It took 18.76mL to reach the phenolphthalein end point and 43.38mL to reach the bromocresol green end point. Deduce the composition of the solution and calculate the concentration of eachsolute in mg/mL of solution.
(c) A 20.00mL solution containing NaOH, Na2C03 and NaHC03, alone or in compatible combination was titrated with 0.1021M standardHCl. It took 20.97mL to reach the phenolphthalein end point and 42.00mL to reach the bromocresol greenend point. Deduce the composition of the solution and calculate the concentration of each solute in mg/mL of solution.
