a sample may contain na2co3 (105.989 g/mol), nahco3 (84.007 g/mol), naoh (39.977 g/mol) or a compatible mixture of these bases. a 0.8412-g sample titrated directly to the methyl orange endpoint required 45.38 ml of 0.1320 m hcl. another 0.8412-g sample was titrated to the phenolphthalein endpoint with the same acid. it required 28.32 ml acid.

can i get a solution that separates the bases, if possible
