Need a little help with chemistry:)
*if you don’t know don’t put anything*

thats a little if u want the answer just look it up on google thats what i do haha : )

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
