Hydrogen cyanide (hcn) is an important industrial chemical. it is produced from methane (ch4), ammonia, and molecular oxygen. the reaction also produces water. balance the equation for this reaction.

the dissociation of nickel hydroxide is follows:

the concentration of hydroxide ion is

the equilibrium constant value of nickel hydroxide is = 6.1 * 10^-^1^6 and thus equilibrium equation can be written as:

thus, concentration of ni is 0.23 * 10^-^4 mol /l
