What reactions will form a precipitate?

What reactions will form a precipitate?

Precipitation reactions occur when the cations of one reactant and the anions of a second reactant found in aqueous solutions combine to form an insoluble ionic solid that we call a precipitate. Most precipitates are formed in a double-replacement reaction.

What is the precipitate resulting from the double-replacement reaction BaCl2 AQ 2NaOH?

What is the precipitate resulting from the double-replacement reaction BaCl2(aq) + 2NaOH(aq)? A blue precipitate forms in the double-replacement reaction Ca(OH)2(aq) + Co(NO3)2(aq).

What was the precipitate when working with BaCl2 and nh4 2co3?

Barium chloride and ammonium carbonate will react to give a white precipitate of barium carbonate and soluble ammonium chloride by double displacement.

How do we name NH4 2CO3?

TCC’s Ammonium Carbonate, also known as baker’s ammonia or hartshorn, is a white, crystalline salt with the chemical formula (NH4)2CO3.

Why can Barium Carbonate cause poisoning in the stomach?

The Ba2+ ion and the soluble compounds of barium (notably chloride, nitrate, hydroxide) are toxic to humans. Although barium carbonate is relatively insoluble in water, it is toxic to humans because it is soluble in the gastrointestinal tract.

Does barium make you sick?

Patients may feel nauseous after a barium swallow test or become constipated. Drinking lots of fluids can help to relieve constipation. Symptoms of nausea should improve as the barium passes through the system.

Is barium hard on kidneys?

Oral “milkshake” barium contrast agents, used in CT scans of the digestive system, do not cause kidney damage, and were not included.

How long does oral contrast stay in your system?

The patient must wait 60-90 minutes after drinking a contrast agent before it is adequately distributed in the bowel. Studies have shown that by requiring oral contrast, the patient’s stay in the ED is extended by far more than 90 minutes.
