A- a water soluble salt forms a precipitant during Group 3 analysis. An acidic solution of this precipitant and NaBiO3 yields a pinkish color. This same salt has no reaction to concentrated H2SO4 or AgNO3, what is the chemical formula for this salt? B- a brown colored salt contains a cation from group 3, it has no reaction with concentrated H2SO4 and produces a soluble product with acidic AgNO3 and acidic BaCl2, this salt is not water soluble. What is the chemical formula for this salt?
