Turning Sugar into Caramel

Explanation:

You turn sugar into caramel by burning sugar. Burning sugar is a chemical change.

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
