Unformatted text preview: Chem 162-2008 Quiz 3 Version A1 1. The K sp for AgBr is 5.0 x 10-13 . The overall formation constant K f of [Ag(S 2 O 3 ) 2 ] 3- is 2.3 x 10 13 . Use these data to calculate the molar solubility of AgBr in 1.0 M Na 2 S 2 O 3 . 2. Give the name/formula of the following compounds. (NOTE en = ethylenediamine = H 2 N-CH 2-CH 2-NH 2 ). a. (NH 4 ) 2 [PtCl 4 ] b. [Co(en) 3 ]Cl 3 c. Tetraamminedihydroxochromium(III) bromide d. Potassium hexacyanoferrate(II) 3. Explain briefly what optical isomerism is. 1 Chem 162-2008 Quiz 3 Version A2 1. The K sp for AgBr is 5.0 x 10-13 . The overall formation constant K f of [Ag(S 2 O 3 ) 2 ] 3- is 2.3 x 10 13 . Use these data to calculate the molar solubility of AgBr in 0.5 M Na 2 S 2 O 3 . 2. Give the name/formula of the following compounds. (NOTE en = ethylenediamine = H 2 N-CH 2-CH 2-NH 2 ). a. (NH 4 ) 2 [PtCl 4 ] b. [Co(en) 3 ]Br 3 c. Tetraamminedihydroxochromium(III) chloride d. Sodium hexacyanoferrate(II) 3. Explain briefly what optical isomerism is. 2 Chem 162-2008 Quiz 3 Version B1 1. The K sp for AgI is 5.0 x 10-16 . The overall formation constant K f of [Ag(NH 3 ) 2 ] + is 1.7 x 10 7 . Calculate the molar solubility of AgI in 1.0 M NH 3 . 2. Give the name/formula of the following compounds. (NOTE en = ethylenediamine = H 2 N-CH 2-CH 2-NH 2 ). a. (NH 4 ) 2 [CuCl 4 ] b. [Co(en) 3 ]Cl 3 c. Diamminetriaquahydroxochromium(III) iodide d. Sodium hexacyanoferrate(II) 3. Explain briefly what cis-trans isomerism is. 3 Chem 162-2008 Quiz 3 Version B2 1. The K sp for AgI is 5.0 x 10-16 . The overall formation constant K f of [Ag(NH 3 ) 2 ] + is 1.7 x 10 7 . Calculate the molar solubility of AgI in 0.5 M NH 3 . 2. Give the name/formula of the following compounds. (NOTE en = ethylenediamine = H 2 N-CH 2-CH 2-NH 2 ). a. (NH 4 ) 2 [CuCl 4 ] b. [Co(en) 3 ]I 3 c. Diamminetriaquahydroxochromium(III) bromide d. Potassium hexacyanoferrate(II) 3. Explain briefly what cis-trans isomerism is. 4 Chem 162-2008 Quiz 3 Version C1 1. Give the name/formula of the following compounds. (NOTE en = ethylenediamine = H 2 N-CH 2-CH 2-NH 2 ). a. (NH 4 ) 2 [PtCl 4 ] Ammonium tetrachloroplatinate(II) b. [Co(en) 3 ]Cl 3 Tris(ethylenediamine)cobalt(III) chloride c. Tetraamminedihydroxochromium(III) bromide [Cr(NH 3 ) 4 (OH) 2 ]Br d. Sodium hexacyanoferrate(II) Na 4 [Fe(CN) 6 ] Common error: In naming the compound, the metal and Roman numeral are listed at the end of the complex ion (e.g., Tetraamminedihydroxochromium(III) bromide). In providing a formula of the compound, the metal is listed at the beginning of the the complex ion (e.g., [Cr(NH 3 ) 4 (OH) 2 ]Br. Common error: A compound (i.e., a coordination compound) has noharge. It is neutral. However, a complex ion has a charge....
