Causes skin irritation.EyesCauses severe eye burns. All potassium salts are soluble, so this is soluble. Contact may irritate the skin and eyes or cause burns. Collectively, the EARs, RDAs, AIs, and ULs are the parameters for the nutrition recommendation system known as Dietary Reference Intake (DRI). [137] A 2008 review suggested that moderate uptake of chromium(III) through dietary supplements poses no genetic-toxic risk. [7][118], In 2005, the U.S. Food and Drug Administration had approved a qualified health claim for chromium picolinate with a requirement for very specific label wording: "One small study suggests that chromium picolinate may reduce the risk of insulin resistance, and therefore possibly may reduce the risk of type 2 diabetes. Most hydroxide are slightly soluble, which really means insoluble. The IDLH (immediately dangerous to life and health) value is 250mg/m3. Sun Industries. 2; Eye Irrit. More hydrogen ions are removed to give ions like [ Cr ( H 2 O) 2 ( OH) 4] and [ Cr ( OH) 6] 3 . It is an orange-red crystal, soluble in water and ethanol, almost insoluble in concentrated nitric acid, and deliquescent in the air. Aggressive dialysis can be therapeutic.

Chromium trinitrate is an inorganic nitrate salt consisting of chromium and nitrate in which the ratio of chromium (in the +3 oxidation state) to nitrate is 1:3 It is an inorganic nitrate salt and a chromium coordination entity. Nitrate is usually not harmful unless it is reduced to nitrite (NO2).Nitrate is used as a fertilizer in agriculture due to its high solubility and biodegradability.
