Potassium dichromate - physicochemical Njirimara na ubi nke na ngwa

Potassium dichromate bụ ọkacha mma na-abụghị caking oroma kristal (mgbe ụfọdụ ọbara ọbara) na-ngwa ngwa soluble na okenye na-ajụ na na-yiri a aghụghọ agịga ma ọ bụ efere. Mgbe inwe mmekọrịta na umi okenye ihe ngwọta na-aghọ acidic.

Potassium dichromate - ukwuu na-egbu egbu, carcinogen na ike oxidants. Ịgba ngwọta nwere ike ibibi anụ ahụ, cartilage, na inhalation nke vapors - karị.
