Question 8Which statement about the complex: dichlorobis(ethylenediamine)cobalt(III) chloride, (FM =285.3 g/mol) is incorrect? (atomic mass of Co = 59 g/mol)?a. It exhibits cis- & trans- isomerismb. It is 1:1 electrolytec. It reacts with 3-fold of AgNO3(aq) to give a white precipitate.d. The %Co in it is 20.65%e. The trans isomer is more stable than cis isomer. Question 7In the gravimetric determination of % Co in Co(acac)s experiment. Why Co(II) solution andKNO2 solution are mixed while they are boiling hot?a) To decompose any unreacted H2O2b) To prevent quick precipitation of Co(II) as K2CO(NO2)4c) To induce recrystallization by evaporating most of the solvent.d) To speed up the digestion process of Co(acac)3e) To help starting the oxidation of Co(II) to Co(III) to produce K3CO(NO2)6
