A sample of water was analyzed through titration with 0.01 N HCI. 150 ml of the water required 30.0 ml of 0.01 N HCI to titrate it to the phenolphthalein endpoint and 14.0 ml of the same HCI solution to titrate it further to the methyi orange endpoint. Assuming the sample contains no calcite particles, what are the total and carbonate alkalinities of the sample in meg/liter and the total alkalinity in mg/liter as CaC0,? Also, what are the concentrations of the major alkalinity species?
