3.40g example of the steel used to deliver 250.0 mL Solution containing Cr2O72−
Expecting all the Cr is contained in the BaCrO4 toward the end.
(0.145 g BaCrO4)/(253.3216 g BaCrO4/mol) x (250.0 mL/10.0 mL) x (1 mol Cr/1 mol BaCrO4) x (51.99616 g Cr/mol/(3.40 g)
= 0.219 = 21.9% Cr
Further Explanation:
Chromium (cr):
Chromium is a compound component with the image Cr and nuclear number 24. It is the primary component in gathering 6. It is a steely-dim, radiant, hard and weak progress metal. Chromium is the principle added substance in tempered steel, to which it includes hostile to destructive properties.
Characterization of chromium:
Classification: Chromium is a progress metal
Color: silver-dark
Nuclear weight: 51.996
State: solid
Softening point: 1907 oC, 2180 K
synthetic properties of chromium:
Chromium is a radiant, fragile, hard metal. Its shading is silver-dark and it tends to be profoundly cleaned. It doesn't discolor in air, when warmed it borns and structures the green chromic oxide. Chromium is unsteady in oxygen, it quickly creates a meager oxide layer that is impermeable to oxygen and secures the metal underneath.
