Question

You now know that [Pb+2] = 0.17 M. Calculate [Cl-].

Refer to equations given in the text to determine the relationship between these ions.

0.17 M
0.26 M
0.34 M
0.51 M

Answer 1

0.34 M

Step-by-step explanation:

Concentration of Pb2+ = 0.17 M

Pb2+ (lead ion) and Cl- (chloride ion) will combine to form lead chloride (PbCl₂)

Based on the chemical formula stoichiometry for every Pb2+ there are 2 Cl-.

Therefore, the relationship between the two ions would be:

[Cl-] = 2([Pb2+])

[Cl-] = 2(0.17 M) = 0.34 M
