the value of ksp for pbcl2 is 1.6. what is the lowest concentration of Cl- that would be needed to begin precipitation of PbCl2
deff fn [24]

Answer:

The minimum concentration of Cl⁻ that produces precipitation is 12.6M

Explanation:

The Ksp of PbCl₂ is expressed as:

PbCl₂(s) → Pb²⁺(aq) + 2Cl⁻(aq)

The Ksp is:

Ksp = 1.6 = [Pb²⁺] [Cl⁻]²

When Ksp = [Pb²⁺] [Cl⁻]² the solution begind precipiration.

A 0.010M Pb(NO₃)₂ is 0.010M Pb²⁺, thus:

1.6 = [0.010M] [Cl⁻]²

160 = [Cl⁻]²

12.6M =  [Cl⁻]

<h3>The minimum concentration of Cl⁻ that produces precipitation is 12.6M</h3>

How many grams of Zn are there in a sample of Zn that contains the same number of moles as a 82.1 gram sample of Ga? grams of Zn
SVEN [57.7K]

Answer:

mass of Zn = 77.0 g

Explanation:

In the sample you have the same moles of Zn and Ga.

The formula for moles is:

Mass = moles*MM \\

Where MM: Molar Mass or Atomic Mass for elements

AM(Ga) = 69.723 amu

AM(Zn) = 65.38 amu

moles of Ga = \frac{Mass}{AM} = \frac{82.1 g}{69.723 amu} = 1.178 mole

mass of Zn = moles*AM=1.178 mole*65.38amu = 77.0 g
