Question 1

Find the solubility (in mol/L) of lead(II) chloride, PbCl2, at 25°C. Ksp = 1.57 × 10–5.

◦ 1.58 × 10–2

◦ 2.50 × 10–2

◦ 6.05 × 10–17

◦ 1.98 × 10–3

◦ 1.99 × 10–2


Question 2

Given the following Ksp values, which statement about solubility in mol/L in water is correct?
Ksp
Ksp
 
PbCrO4
2.0 × 10–16
Pb(OH)2
1.2 × 10–15
 
Zn(OH)2
4.5 × 10–17
MnS
2.3 × 10–13


◦ PbCrO4, Zn(OH)2, and Pb(OH)2 have equal solubilities in water.
◦ PbCrO4 has the lowest solubility in water.
◦ The solubility of MnS in water will not be pH dependent.
◦ MnS has the highest molar solubility in water.
◦ A saturated PbCrO4 solution will have a higher [Pb2+] than a saturated Pb(OH)2 solution.

ACTH levels are normally highest in the early morning (between 6 and 8 A.M.) and lowest in the evening (between 6 and 11 P.M.). Therefore, a doctor who suspects abnormal levels looks for low ACTH in the morning and high ACTH in the evening.

Once thought to have neurofibromatosis, Joseph Merrick (also known as "the elephant man") is now, in retrospect, thought by clinical experts to have had Proteus syndrome. This endocrine disease causes continued and abnormal growth of the bones, muscles, skin, and so on and can become completely debilitating with severe deformities occurring anywhere on the body.
