A 3cm3 sample of a solution of the nitrate of metal Q , concentration 1 mol/dm3, was added to 2cm3 of potassium fluoride, conc. = 1mol/dm3.
When the precipitate settled its height was measured. The experiment was then repeated using different volumes of potassium fluoride solution.
A diagram is displayed with the question. It shows that at 6cm3 the precipitates height stops increasing.
What is the formula of the fluoride of metal Q ??
