The flow of blood to the arteries of the body is impaired when aortic stenosis exists. Ultimately, this can lead to heart failure. Aortic stenosis occurs three times more commonly in men than women. Picture of heart and valves -- aortic valve stenosis.
Ammonium thiocyanate is colorless lustrous monoclinic flaky or columnar crystal with the chemical formula being NH4SCN and the molecular weight of 76.12. At 92 â, it is rhombohedral crystal with the melting point of 147 â (decompose at 170 â), the relative density of 1.3057 and the refractive index of 1.685.
Thiocyanate forms a red complex with ferric ions in the presence of nitric acid.
