What do the Acetone and Acetoacetate and b-hydydroxybutyrate form in body?

Acetoacetate, beta-hydroxybutyrate, and their spontaneous breakdown product, acetone, are known as ketone bodies. The ketone bodies are released by the liver into the blood.

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

i believe the answer is 5,000
