Ag2CrO4
Silver chromate/Formula
What causes Ag2CrO4?
Silver chromate is an inorganic compound with formula Ag2CrO4 which appears as distinctively coloured brown-red crystals. The compound is insoluble and its precipitation is indicative of the reaction between soluble chromate and silver precursor salts (commonly potassium/sodium chromate with silver nitrate).
What is the charge of Ag2CrO4?
Each silver atom has a +1 charge while chromate has a -2 charge (a -1 on each of the oxygen atoms).
Is Ag2CrO4 s hazardous?
Hazardous in case of skin contact (irritant), of ingestion. Over-exposure by inhalation may cause respiratory irritation. Potential Chronic Health Effects: Non-corrosive for skin.
Why is silver chromate red?
Most probably, therefore, the reason for the red colour of silver chromate is that the first electric-dipole- allowed chromate transition shifts about 5000 cm -1 to lower energy compared with the yellow potassium salt.
Is Ag2CrO4 soluble in water?
Although Ag2CrO4 is insoluble in water, it is soluble in dilute HNO3.
Is silver nitrate hazardous?
► Exposure to Silver Nitrate can cause headache, dizziness, nausea and vomiting. to transport Oxygen, causing headache, fatigue, dizziness, and a blue color to the skin and lips (methemoglobinemia). Exposure to very high levels can cause trouble breathing, collapse and even death.
Is red silver chromate a precipitate?
When clear, colorless silver nitrate solution is added to transparent, yellow sodium chloride solution, red silver chromate precipitates. Therefore, when the soluble salts silver nitrate and sodium chromate are mixed, insoluble silver chromate forms and precipitates out. …
Is silver chloride soluble in water?
Silver chloride is a chemical compound with the chemical formula AgCl. This white crystalline solid is well known for its low solubility in water (this behavior being reminiscent of the chlorides of Tl+ and Pb2+).
