Chromatography separates a mixture by adding a liquid (usually water) to separate out the pigments of the mixture/ink. The inks separate accordingly because as the water picks up and carries the pigments, each pigment travels at a different speed. This causes differentiation to appear, which causes the pigments to separate and show accordingly.
Answer:
The electrode that removes ions from solution
Explanation:
Each electrochemical cell consists of an anode and a cathode. Oxidation occurs at the anode and reduction occurs at the cathode.
At the anode, ions move from the electrode into the solution while at the cathode ions move from the solution to the electrode.
At the cathode, metal ions accept electron(s) and become deposited on the electrode hence this electrode removes ions from solution. This is reduction.
Na would form a 1+ ion losing its electron to the Cl to make a Cl- ion. Gives the molecule NaCl
PbCl₂ ⇄ Pb²⁺ + 2 Cl⁻
Initially 0 5.4 M
Change -x + x + 2x
Equilibrium x 5.4 + 2x
Ksp = [Pb²⁺] [Cl⁻]²
1.6 x 10⁻⁵ = x (5.4 + 2x)²
since x <<<< 5.4 so 2x + 5.4 = 5.4
1.6 x 10⁻⁵ = x (5.4)²
x = 5.48 x 10⁻⁷
[Pb²⁺] = 5.48 x 10⁻⁷ M
