Apaint mixture containing 25.0% of a pigment and the balance water sells for r22.00/kg, and a mixture containing 12.0% pigment sells for r12.00/kg. if a paint retailer produces a blend containing 17.0% pigment, for how much (r/kg) should it be sold to yield a 10% profit? start by drawing a flow diagram of the process.

the answer is true. hope it .

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
