Consuming foods high in these minerals, is always a safer and better option than consuming supplements. The table given below enlists the foods that are rich in potassium, calcium and magnesium, along with the amount of these minerals, contained in each.eople suffering from hypertension should increase the intake of potassium by consuming foods that are rich in potassium. Even though supplements that contain potassium, calcium and magnesium, are available, they should be consumed in limited amounts, and only after consulting a physician.
Barium sulfate (or sulphate) is the inorganic compound with the chemical formula BaSO 4. It is a white crystalline solid that is odorless and insoluble in water. It occurs as the mineral barite, which is the main commercial source of barium and materials prepared from it.
Sulphates are usually soluble in water except for Ag2SO4, BaSO4, CaSO4 and PbSO4 (lead sulphate).Hope that helps (: PbSO4 is sparingly soluble in water, its solubility at 298K is about 1.4E-4 mol/L, a very small value. So its not insoluble, it just has a very small solubility.lthough the anion (SO4 2-) is found on the solubility chart, you must remember that there are exceptions i.e. the silver group (Silver ion-A â¦ g+, Mercury (I) ion-Hg2 2+, and Lead (II) ion-Pb 2+) Since the Lead (II) cation is in the chemical formula Lead (II) Sulfate (PbSO4), it will be INSOLUBLE in water.
