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.
What else can I help you with?
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 it legal to own potassium cyanide in the US?
Oh, my friend, it's important to focus on the beauty of life and nature. Potassium cyanide is a highly toxic substance and should only be handled by professionals for specific purposes like scientific research or industrial use. Let's paint a happy little tree instead and appreciate the wonders of the world around us.
How does cyanogen chloride differ hydrogen cyanine?
Cyanogen chloride differs from hydrogen cyanide in chemical structure and formula. Hydrogen cyanide is HCN, composed of the elements hydrogen, carbon, and nitrogen. Cyanogen chloride is ClCN, composed of the elements chlorine, carbon, and nitrogen. From the formulas and structures it is possible to infer that cyanogen chloride is denser as a gas, and less likely to produce cyanide ions (CN-) than hydrogen cyanide.
What is the color of potassium chlorate?
Potassium chlorate is a white or colorless crystalline solid.
Sodium reacts with water less vigorously than potassium. why?
Sodium reacts less vigorously with water compared to potassium because sodium has a larger atomic size and lower reactivity than potassium. This results in a slower reaction rate and less violent release of hydrogen gas.
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.
What chemical can be used in jewelry making to replace Potassium Cyanide to frost polished silver?
Thiourea can be used as a safer alternative to Potassium Cyanide for frosting polished silver in jewelry making. It is less toxic but still effective in achieving the desired frosted finish on silver.
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.
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

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.
What are the mechanisms of the body for getting rid of cyanide?
Natural mechanism for getting rid of cyanide involves rhodanase, which is an enzyme occurring naturally in mammals. It combines cyanide with thiosulfate, producing comparatively harmless thiocyanate. Other antidotes include hydroxocobalamin and sodium nitrite which release the cyanide from the cytochrome system.
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.
How does cyanogen chloride differ hydrogen cyanine?

Cyanogen chloride is ClCN, composed of the elements chlorine, carbon, and nitrogen.

Does poison becomes less poisonous after its expiry date?
No.
