The two properties of the ink components that determine their movement along the chromatography paper/fabric are:
the solubility of ink constituent in chemical solvent.
the mixture of colour constituents in the ink.
Explanation:
Chromatography is the process in which the chemicals of the mixture are separated on the basis of constituents.
Capillary action let the colors of ink separate into their constituents. When ink is subjected to solvents it gets dissolve and gets separated.
The property of ink that led to determine their movement is:
Ink is made of many dyes of different colours, pigments etc.
The chemicals that has the best solubility in the chemical will move up on the chromatography paper and fabric.
Answer:
648.68 mg
Explanation:
The reaction that takes place is:
- FeCl₃ + 3NaOH → Fe(OH)₃ + 3NaCl
First we<u> calculate how many moles of each reactant were added</u>, using the <em>given volumes and concentrations</em>:
- FeCl₃ ⇒ 100 mL * 0.240 M = 24 mmol FeCl₃
- NaOH ⇒ 100 mL * 0.182 M = 18.2 mmol NaOH
24 mmol of FeCl₃ would react completely with (24 * 3) 72 mmol of NaOH. There are not as many NaOH mmoles, so NaOH is the limiting reactant.
Now we <u>calculate how many moles of Fe(OH)₃ are formed</u>, using the <em>moles of the limiting reactant</em>:
- 18.2 mmol NaOH * = 6.07 mmol Fe(OH)₃
Finally we <u>convert 6.07 mmol Fe(OH)₃ to grams</u>, using its<em> molar mass</em>:
- 6.07 mmol Fe(OH)₃ * 106.867 mg/mmol = 648.68 mg
