Question

Salts of barium, barium sulfate Particularly, When applied orally and because of its low solubility (Ksp = 1 x 10 ^ -10) Increase contrast for X-rays in medical diagnosis of the digestive system. Considering que Were reacted 7 × 10 -5 moles of CaCl2 with an equivalent amount of Na2SO4 in sufficient distilled water to make 1000 mL, calculate the mass of BaSO4 produces, the precipitate is filtered and dried

Answer 1

Your question is about as clear as mud. You should learn how to ask a question. I assume, put into plain English, you have 7E-5 mols CaCl2 and 7E-5 mols Na2SO4, how much BaSO4 is produced. The answer is none. You can't produce BaSO4 unless barium ion is reacted with a sulfate. You may have meant BaCl2 instead of CaCl2.

Answer 2

Barium salts, especially the barium sulphate, when applied by the oral route and due to its low solubility (Kps = 1 × 10E-10), increase the contrast to the X-ray, in medical diagnosis of the digestive system. Considering that were-reacted 7 × 10E-5 moles BaCℓ2 with equivalent amount of Na2SO4) in distilled water enough to make up to 1000 mL, calculate the mass of BaSO4 produced, if the precipitate is filtered and dried


Im so sorry
