Why is potassium Ferricyanide less poisonous than potassium cyanide?
Wiki User
∙ 13y ago
Cyanide is highly poisonous because it binds irreversibly to the iron in the haemoglobin of the red blood cells, preventing them from transporting oxygen. In the ferricyanide, the cyanide ligands are already bonded strongly to an iron atom, so are not as freely able to bond to haemoglobin if they enter the bloodstream. Ferricyanides can however become very dangerous on reaction with acids, which can re-release the cyanide ligands.

Which is less reactive gold or platinum?
Platinum is less reactive, by reacting with aqua regia only in the hot while gold not. Platinum potassium cyanide is not known while Gold potassium cyanide is obtained quite simply. In contrast, Platinum is somewhat lower on the electromotive scale - 1.2v against 1.5-1.6v for gold
Is potassium more or less active than sodium?
Potassium is more reactive than sodium
Does silver react with potassium nitrate?
No silver cannot react. It is less reactive than potassium
Why use of alcohol is preferred over mercury in thermometers?
Alcohol is less expensive and the compounds formed from oxides of Mercury are poisonous while alcohol is less problematic.
What is the color of potassium chlorate?
it is a colour less powder.
What happens when copper metal reacts with potassium cyanide?
Copper metal is less reactive than potassium so it will not react with potassium cyanide.

Can silver potassium cyanide kill you?
Let's clear one thing up first: potassium cyanide is a solid (powder). At room temperature, in its pure form, it can't be drunk.Of course, one can take a tablespoon of potassium cyanide and dissolve it in a glass of water, THEN drink the resulting solution. The result would be a quick DEATH, because there is more than a fatal dose of cyanide in one tablespoon of the compound.The gas chamber, which was used as an execution method by some US states until quite recently, makes use of potassium cyanide. Pellets or powdered potassium cyanide are dropped into a dish filled with sulfuric acid, which is placed underneath the chair of the condemned prisoner. The potassium cyanide quickly reacts with the acid, and releases hydrogen cyanide, which is the gas that poisons and kills the prisoner.Potassium cyanide is a common and useful laboratory chemical, despite its toxicity. As with all laboratory chemicals, it should be used with care and respect.
Why does cyanide kill so quickly?
Cyanide is highly toxic, wikipedia says 1.5mg per kg body weight. There are lots of antidotes available- if using cyanide in the laboratory it is mandatory to have the antidote close to hand and people need training in how to use it.
Does cyanide cause pain?
Sometimes. Injestion of toxic cyanides like hydrogen cyanide, potassium cyanide, and sodium cyanide, in less than lethal doses, can cause headaches (and/or eupohoria, shortness of breath, vertigo, confusion, adema, paralysis)- however, a highly concentrated dose would act so quickly that it's unlikely the potential headache would have a chance manifest before the subject falls into a coma then dies one to three minutes later.
How fast can chlorine gas kill someone?
The LD50 (the dose that'll kill half the people who take it) of potassium ferricyanide is 2970mg/kg, which is very nearly the same as the LD50 of table salt. I wouldn't recommend eating any of it - it'll make you sick as a dog if you do - but it won't kill you.
What is the difference between alkaline zinc plating and cyanide zinc plating?
alkaline zinc plating is less expensive to prepare and maintain , and it do not cause pollution as cyanide zinc plating.
Why does increasing extracellular potassium ion cause membrane potential to change to a less negative value?
the membrane potential became less negative because less potassium ions went out of the cell (since the extra cellular space has higher concentration of potassium, and potassium goes down its concentration gradient, from high concentration to low concentration). since less potassium (K+)which is positive, left the cell more it became more positive (less negative)
Difference between chemical and ozone treatment of cyanide?
Ozone is a chemical, so there is no difference.Ozone oxidizes cyanide to a less biologically toxic state (very rapid reaction), however organisms will (eventually) remove the extra oxygen to "breathe", making cyanide elsewhere.
Is potassium more or less active than sodium?
Potassium is more reactive than sodium
Does silver react with potassium nitrate?
No silver cannot react. It is less reactive than potassium
Is zinc less reactive with potassium based from activity series of metals?
Yes, zinc is LESS reactive than potassium based on the activity series.
