(10 pts) In a double indicator titration analysis of a carbonate mixture, the following data were obtained: Volume of aliquot (mL) Concentration of HCl (M) Vahtk (mL) Vacz (mL) 75.00 0.5445 0.00 37.13 Determine the concentration (in M) of NaOH, NaHCO3, and Na2CO3 present in the mixture. (8 pts) Using the Mohr's method of titration, determine the concentration of NaCl (58.45 g/mol), in ppt, present in 25.00 mL of a sample when 24.93 mL of 0.0097 M AgNO3 was used to reach the endpoint.
