Question

Calculate the solubility at 25 °C of Ni(OH), in pure water and in a 0.0030 M NaOH solution. You'll find K, data in the ALEKS Data tab. Round both of your answers to 2 significant digits, solubility in pure water: 0을 solubility in 0.0030 M NaOH solution: Data BaSO4 caco CaF2 Co(OH)2 CuBr Cuco; Fe(OH)2 PbCO3 PbCro4 PbF2 Mg(OH)2 NI(OH)2 AgBros Ag2003 1.08x10-10 3.36X10-9 3.45x10-11 5.92 x 10-15 6.27X10-9 1.4x10-10 4.87x10-17 7.40X10-14 2.8x10-13 3.3x10-8 5.61x10-12 5.48x 10-16 5.38x10-5 8.46x10-12 1.77x10-10 1.12x10-12 5.60x10-10 1.46x10-10 3.0x10-17 5.35x10-13 1.77x10-10 AgaCIO Srco, ZnCoy Zn(OH)2 AgBe Auc [+] Complex lon formation constants (K)

ksp=Ni(OH2)-->5.48*10^-16

Answer 1

-16 3 . 113 * Ksp of Ní (04), = {n9+23 204] Kep Of Ni COH) = (25)? =453, In pure wats, kip of NICOH = 5.48% 10" 5.48 xio 16 = 453. . ..S= (5:48 to")* = 6.36x16m. sa solubility in pure wals = [ 6.36x100 m. In 0.003m. Naot solusiai [OH-] 0.003m. ... 5.48 x16 16 = Capp+2] * (0.003)2 5:48 Kicks = 5.x (0.003)2 i s = solubility in a wewe > 16.088 X10 ML Nooh solution »
