A Stock solution of KOH is mol/dm - 3. X cm3 aliqout is added to approximately 200.0cm3 of water in a volumetric flask and the volume of the solution is made up with water to 250cm3 . What is the value of X If the final concentration is 0.05mol/dm- 3?

listen, you cant how young you were.

"you didn't chose the stud life. the stud life chose you."

c) should be the answer.

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
