    I need to design an experiment where I have approximately 2g mixture of sodium nitrate and calcium nitrate and need to find the mass of each. I'm not entirely sure how to do this as my previous idea isn't going to work. Any help would be appreciated.

    I was thinking along the lines of titrating the precipitate, then back titrating but I don't know what to titrate with as I was going to titrate with sodium hydroxide but that won't work.

    precipitate the calcium ions using sulfate ions then collect, dry and weigh the mass of the calcium sulfate.
