B The Molar Conductivities 1 Of 0 2 M Formic Acid Hcooh Aq And 0 002 M Lithium Carbonate Li2co3 Was Measured At S 1 (95.72 KiB) Viewed 27 times

b) The molar conductivities (1) of 0.2 M formic acid, HCOOH (aq) and 0.002 M lithium carbonate, Li2CO3 was measured at same value of 3.81 mS m2 mol-1. By referring to Table 1, calculate: i) molar conductivity of infinite dilution (N.) for HCOOH (aq) and Li2CO3 (in unit mS m2 mol-). (2 marks) ii) degree of dissociation (a) for HCOOH (aq) and Li2CO3 (aq) (2 marks) iii) dissociation constant (Ka) for HCOOH (aq) and Li2CO3 (aq) (2 marks) Table 1 Limiting ionic conductivities (10) in water at 298 K Cations lo (m5 m2 mol-1) Anions lo (m5 m2 mol-) H+ 34.96 ОН: 19.91 K+ 7.35 CO3 13.86 Lit 3.87 HCO; 5.46 NH4+ 7.35 CH3CO 4.09 H 34.96 OH 19.91 Table 1
