    Past paper question

    I am doing a past paper and do not get question 2 of the multiple choice
    https://thsconline.github.io/s/?view...010%20w.%20sol
    Why isn't the answer A is it because NaCl is still soluble in water?
    Thanks

    Yes. Precipitation occurs because not all ionic compounds are soluble and that results in an insoluble compound being precipitated, (if the separate ions are added together in solution).
