Is thiocyanic acid a strong acid?
It is a moderately strong acid, with a pKa of 1.1 at 20 °C and extrapolated to zero ionic strength.
Is thiocyanate toxic?
Thiocyanate is 100-fold less toxic than cyanide and is excreted by the kidney with an approximate elimination half-life of 2.7 days. Renal insufficiency prolongs elimination. Symptoms of thiocyanate toxicity are primarily neurologic.
Why is it called thiocyanate?

Is hmno4 a strong acid?
As a strong acid, HMnO4 is deprotonated to form the intensely purple coloured permanganates. Potassium permanganate, KMnO4, is a widely used, versatile and powerful oxidising agent.

What is thiocyanate found in?
6.6 Glucosinolates. Major glucosinolates are goitrin, isothiocyanates, and thiocyanates (Fig. 10.2) that naturally exist in cruciferous plants such as cabbage, kale, broccoli, and green leafy vegetables. Glucosinolates are also found in oilseed crops such as rapeseed and soybean meal.
How does nitroprusside cause cyanide toxicity?
Nitroprusside is rapidly hydrolyzed (half-life, 11 minutes) and releases free cyanide, which normally is converted quickly to thiocyanate by rhodanase enzymes in the liver and blood vessels.
