2. A concentrated solution of a yellow compound in methylene chloride is added to a chromatographic column. The elution is started using hexane as the solvent. But after 6 liters of hexane have passed through the column, the yellow band has not moved. What can be done to move the band at an acceptable rate?\

what are the statements

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
