The cyanide ion binds to the iron that red blood cells use to carryoxygen around the body, thus interfering with the blood's ability to deliveroxygen to the tissues. It is this toxicity that has made the use of cyanide in goldmining controversial. Most states now ban the use of cyanide in leaching goldout of low-grade ore.

Acid Base Titration

An acid-base titration is the method of quantitative analysis for determining the concentration of an acid and base by exactly neutralizing it with a standard solution of base or acid having known concentration.
