In a paper chromatography analysis, three pigments, a, b, and c, were dissolved in ivent. a is slightly polar, b is highly polar, and c is moderately polar. list in order how these will appear on the surface of the chromatography strip starting from the applied spot at the origin line.

i think the answer is terrae but not 100 percent sure. ▓▬▬ §

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

yes the answer is total mass in unchanged   : )
