    Why is calcium stearate (soap scum) insoluble in water

    Based on electronegativity values, there's very little difference between atoms of potassium, sodium and calcium/magnesium, not enough to change the polarity. The ion from the hard water bonds with an oxygen atom, and the electronegativity difference between an atom of calcium/magnesium and an atom of oxygen is still large enough for it to be polar at the same end as it was with sodium/potassium.
