3.
Calculate the molar solubility of Agl in a 0.1 M NaCN solution.
Agl(s)
Ag(aq) + (aq)
Ksp = 8.3×10-17
Ag (aq) +2CN (aq) Ag(CN)2(aq)
K₁ = 1.0x1021
4.
A 1.500-g sample of limestone rock is pulverized and treated with 30.00 mL of a 1.04 M HCI
solution. The excess acid is titrated with a 1.01 M NaOH solution, requiring 11.65 mL to reach a
phenolphthalein end point. Calculate the weight percentage of CaCO3 (100.09 g/mol) in the rock sample.
